Launch-week issue desk
These rows separate confirmed fixes, official guidance, and report buckets that still need repeated platform-specific reports.
| Issue bucket | Platform | Status | Source type | First workaround | Checked |
|---|---|---|---|---|---|
| Multiplayer: clients unable to demolish walls | All platforms (co-op) | Partially fixed May 15 | SteamDB patch notes | May 15 hotfix significantly improved this issue. Unknown Worlds notes it should be completely resolved in the next patch. If still occurring, try having the host demolish walls, or wait for the upcoming full fix. | May 15, 2026 |
| "I can't eat food, raw fish damages my health" | All platforms | Not a bug — intended mechanic | Confirmed in EA launch build | Subnautica 2 starts every save with Digestive Incompatibility. Read Anita in NOA, swim northeast from the Lifepod toward Anita black box, interact with the Angel Comb central pod, and Digestion unlocks permanently. Use the Angel Comb Digestion Gene route for the step-by-step path. | June 9, 2026 |
| Install button or entitlement not visible after release | Steam, Epic, Xbox, Game Pass | Live triage | Storefront / official timing | Confirm the account owns the game or has an active Game Pass tier, then restart the launcher, Xbox app, or console store. If the listing still shows the wrong state, compare with the chosen platform status before calling it a game bug. | May 20, 2026 |
| Game Pass access confusion | Xbox Series X|S, Xbox on PC, cloud, PC Game Pass | Live triage | Xbox Wire / Game Pass listing | Check whether the subscription is Game Pass Ultimate or PC Game Pass, then confirm the Game Preview listing appears on the correct Microsoft account and device family. | May 20, 2026 |
| PC performance or launch crash | Windows PC | Community watch after Hotfix 3 | Steam store/review radar + community reports + Hotfix 3 | Hotfix 3 fixes rare startup crashes and several DLSS / Frame Generation issues, while Hotfix 2 improved Epic visual setting performance. Newer driver-timeout, hard power-off, old-save freeze, overlay, or post-patch crash reports still need CPU, GPU, driver, temperature, power-supply, overlay, crash-log, settings, save-state, and whether the issue happens on a new save before being treated as the same bug. | June 7, 2026 |
| DLSS crash, DLSS settings not saving, or Frame Generation missing | Windows PC (mostly Nvidia / DLSS users) | Fixed in Hotfix 3 | Steam appnews: Early Access Hotfix 3 | Update to Hotfix 3, then recheck DLSS mode, Frame Generation availability, and whether graphics settings persist after a restart. Unknown Worlds also upgraded DLSS to 4.5 in this patch. If DLSS still crashes, report GPU model, driver version, resolution, fullscreen/window mode, Frame Generation state, and whether the issue happens on a clean settings file. | June 2, 2026 |
| Hammerheads following Tadpole lights back toward bases | All platforms | Adjusted in Hotfix 2 and Hotfix 3 | Steam appnews: Hotfix 2 + Hotfix 3 | Hotfix 2 reduced attraction to Tadpole lights. Hotfix 3 adds that Hammerheads no longer attack unpiloted Tadpoles, but can still take an interest in Tadpoles. Update before testing base-adjacent behavior, then record whether the Tadpole is piloted, unpiloted, docked, lit, or near a base. | June 2, 2026 |
| Tadpole exploration teleporting player back to base | All platforms | Fixed in Hotfix 2 | Steam appnews: Early Access Hotfix 2 | Update to Hotfix 2 first. If teleporting still occurs, record biome, depth, whether you were piloting, docking, exiting, loading near a base, or joining as a co-op client. May 30 community leads mention base-teleport / dock-load wording, so keep those nearby symptoms in this bucket until a clean repro confirms a separate issue. | May 30, 2026 |
| Infinite oxygen after hunger or thirst death while piloting Tadpole | All platforms | Fixed in Hotfix 2 | Steam appnews: Early Access Hotfix 2 | Hotfix 2 targets this specific death-state bug. Avoid using old saves or console states as final confirmation until you can reproduce the issue on the Hotfix 2 build without mods and with a clean death / respawn path. | May 23, 2026 |
| Crash when losing connection from multiplayer game | Co-op sessions | Fixed in Hotfix 2 | Steam appnews: Early Access Hotfix 2 | Update all players, then recheck disconnect behavior with host and client roles separated. If a crash still happens, note who disconnected, whether the world saved, and whether the crash occurred on host, client, or both. | May 23, 2026 |
| Client reverts to previous position when rejoining multiplayer | Co-op clients | Fixed in Hotfix 3 | Steam appnews: Early Access Hotfix 3 | Update every player to Hotfix 3, then test rejoining with host and client roles separated. If position rollback still happens, record the old and new location, save/load timing, whether the client was in a Tadpole or base, and whether the host stayed online continuously. | June 2, 2026 |
| Random crash in late-game region | All platforms | Fixed in Hotfix 2 | Steam appnews: Early Access Hotfix 2 | Hotfix 2 includes a fix for a random crash in the late-game region. If the crash persists, collect route, biome, save age, graphics settings, Tadpole state, and whether the session is solo or co-op before assuming it is the same issue. | May 23, 2026 |
| Rare crash when starting games | All platforms | Fixed in Hotfix 3 | Steam appnews: Early Access Hotfix 3 | Hotfix 3 includes a fix for a rare crash when starting games. If a startup crash remains, separate it from DLSS, driver, overlay, file-integrity, and old-save cases before filing a report. | June 2, 2026 |
| Startup error guidance for AMD GPU / DirectX 12 cases | Windows PC (AMD GPU / DirectX 12) | Updated in Hotfix 1 | Steam appnews: Early Access Hotfix 1 | Hotfix 1 updates the crash-on-startup error pop-up to provide more guidance for AMD graphics cards and DirectX 12 issues. Update the game first, then update GPU drivers and follow launch-troubleshooting steps if the new message still points to a local graphics or DirectX problem. | May 20, 2026 |
| Infrequent crash related to Ping feature | All platforms after hotfix rollout | Fixed in Hotfix 1 | Steam appnews: Early Access Hotfix 1 | Restart the game and confirm the hotfix has reached your storefront. Unknown Worlds notes Xbox rollout can lag while certification clears, so Xbox players may need to wait for the platform update. | May 20, 2026 |
| Steam and Xbox players see different game version / cannot crossplay after Hotfix 1 | Steam + Xbox / Game Pass crossplay | Hotfix rollout mismatch | Steam discussion + hotfix rollout notes | If Steam updates first but Xbox or Windows Store has not received the same hotfix yet, crossplay can fail even when both players own the game. Hotfix 3 repeats that worldwide rollout may take time, so check pending updates and build versions on every platform before changing NAT, router, or account settings. | June 2, 2026 |
| Steam Deck controller sensitivity feels too low | Steam Deck / handheld controls | Community demand signal | Steam Discussions + Deck verification context | Treat this as a settings and input-profile check first, not final confirmation that the Verified rating is wrong. Check in-game look sensitivity, Steam Input layout, gyro state, frame-rate cap, and whether the same save feels different on a desktop controller. If reporting it, include Deck model, controller layout, FPS cap, graphics preset, and whether the issue is camera look, cursor movement, or vehicle steering. | June 4, 2026 |
| FOV slider or camera comfort request | All platforms, especially PC and handheld | Community demand signal | Steam Discussions | This is a feature-request bucket until Unknown Worlds publishes a setting or roadmap note. Check the current Display, Graphics, Accessibility, and Controls menus before assuming the option is absent in your build, then report motion-sickness or camera-comfort feedback with platform, resolution, aspect ratio, seated distance, and FOV preference. | June 4, 2026 |
| Tadpole mount or chassis state breaks after death / co-op reload | Co-op vehicle progression | Community watch after Hotfix 2 | Reddit / WebSearch reports + Hotfix 2 context | Hotfix 2 fixes the specific infinite oxygen bug after hunger or thirst death while piloting a Tadpole, but broader mount / chassis state reports still need repeatable player reports. If a player cannot enter any Tadpole after dying, docking, loading near a base, or respawning near a vehicle, have every player leave cleanly, make the host quit fully, reload from the main menu, then let clients rejoin after the host is back in-world. Reports mentioning reprint, broken save, base teleport, dock-load, or lost vehicle-control wording should stay in this same watch bucket until a clean repro separates them. | May 30, 2026 |
| Co-op desync or extreme FPS drop around Alien Ruins / Tadpole chassis setups | Co-op sessions | Pattern needed | Recent Reddit reports | Several reports connect late-route co-op desync, very low FPS, Alien Ruins bases, or mixed Tadpole chassis states, but the trigger is not confirmed. Record host platform, client platform, biome, chassis type, base location, and whether analytics / crash-upload settings differ before calling it a fixed workaround. | May 21, 2026 |
| Post-hotfix launch or save-load freeze | Windows PC / Steam | Under watch after Hotfix 2 | Recent Reddit reports + Hotfix 2 context | Update to Hotfix 2, verify files, update GPU drivers, disable overlays, and try a clean launch before editing local files. If an older save freezes after loading, back up the full save folder before trying config cleanup, .bak recovery, or a new-save comparison. | May 23, 2026 |
| Hot Caves collision gap or out-of-bounds fall | All platforms | Single-report watch | Community report lead | A May 30 community lead mentions a Hot Caves no-collision / out-of-bounds path, but this is not confirmed as a repeatable bug. If it happens, avoid saving while out of bounds, reload the last safe save, then report the biome, depth, route, coordinates if available, vehicle state, and whether the same path fails twice. | May 30, 2026 |
| GeForce NOW launch or session error after Hotfix 1 | Cloud gaming / GeForce NOW | Community watch | NVIDIA launch support + Reddit reports | NVIDIA listed Subnautica 2 as a day-and-date GeForce NOW title, so access should exist when the cloud build is healthy. If the game errors only on GeForce NOW after a hotfix, wait for the cloud image to refresh, try a fresh session, and compare against local Steam or Xbox behavior before reinstalling anything. | May 21, 2026 |
| Save appears deleted, missing, or rolled back | Windows PC / Steam | Community workaround | Reddit .bak save discussion | Before renaming or replacing anything, copy the full Subnautica 2 save folder somewhere safe. Some players report restoring a backup by checking the local SaveGames folder for .bak files, but this should be treated as a last-resort recovery path, not a guaranteed official fix. | May 21, 2026 |
| Cannot kill hostile creatures / Survival Tool does not behave like a weapon | All platforms | Not a bug — design direction | Unknown Worlds community letter | Unknown Worlds has acknowledged creature encounters can feel frustrating, but the announced direction is tuning aggression timing, aggro range, flare effectiveness, Survival Tool effectiveness, and vehicle/base interactions. Do not expect a patch that turns predator encounters into traditional weapon combat; use avoidance, flares, route planning, and future mitigation-tool tuning instead. | May 21, 2026 |
| Nibblers or Marrowbreaches feel different after the latest patch | All platforms | Creature tuning in Hotfix 3 | Steam appnews: Early Access Hotfix 3 | Hotfix 3 reduces Nibbler perception range and movement speed, increases their circling time, Multitool sensitivity, and damage, and makes Marrowbreaches hit harder but attack less often. Treat exact safe-distance, damage, and stun timing advice as in-game check work until encounter data is confirmed. | June 2, 2026 |
| Strike Armor modification stacks into a broken state | All platforms | Fixed in Hotfix 3 | Steam appnews: Early Access Hotfix 3 | Hotfix 3 fixes Strike Armor modification stacking additively in a way that could become game-breaking. If armor values still look wrong, record the exact biomod loadout, whether it was equipped before patching, and whether removing / re-equipping changes the value. | June 2, 2026 |
| Goggles remain visible after exiting Tadpole Haul Chassis as passenger | All platforms | Fixed in Hotfix 3 | Steam appnews: Early Access Hotfix 3 | Update to Hotfix 3 before testing this visual bug. If it persists, record host/client role, passenger state, chassis type, first-person camera state, and whether leaving/rejoining the session clears the goggles. | June 2, 2026 |
| Launch crash on some AMD Radeon RX 7000/9000 setups | Windows PC (AMD GPU) | Driver issue + community watch | AMD driver notes / Steam appnews / June 7 bug radar | Update the game first, then record the exact Adrenalin version before changing drivers. Newer RX 7000 / RX 9000 style driver-timeout reports, including RX 7600 leads, should stay in this bucket until the driver version, overlay stack, temperature, save state, and crash-log pattern are clear. Avoid treating one player driver rollback as a universal fix; compare against launch-troubleshooting steps and clean-save behavior before escalating as a game regression. | June 7, 2026 |
| Hostile creature mitigation feels unclear or unreliable | All platforms | Balance watch after Hotfix 2 | Steam appnews: community letter + Hotfix 2 | Unknown Worlds has started the tuning pass by reducing Hammerhead attraction to Tadpole lights, and still says more creature-balance changes are coming. Treat creature routes as patch-sensitive and avoid writing fixed behavior values until the current build is tested. | May 23, 2026 |
| Telemetry, Terms of Service, and Privacy Policy prompt after update | All platforms | Official Hotfix 2 change | Steam appnews: Early Access Hotfix 2 | Hotfix 2 revises sections of the Terms of Service and Privacy Policy, so the game prompts players to re-accept. The note also says analytics can be turned off from settings, adds an English telemetry callout, and points players to a FAQ plus fan content creator guidelines. Treat this as policy / settings context, not a gameplay bug. | May 24, 2026 |
| Co-op invite or cross-platform session fails | Steam, Epic, Xbox, Xbox on PC | Pattern needed | Community reports / official updates | Record host platform, guest platform, account path, region, error text, and whether solo launch works. Compare with server status before changing network settings. | May 11, 2026 |
| Launch-week reward or Twitch Drop missing | All official platforms | Separate from access bugs | Unknown Worlds reward posts | Keep purchase date, storefront, account link status, Twitch account, and platform account separate. Do not mix Twitch Drop entitlement checks with install or co-op bugs. | May 11, 2026 |
⚡ Performance issue
Compare your system with official minimum and recommended specs before changing settings.
👥 Co-op issue
Check cross-platform notes, platform accounts, and known multiplayer updates first.
Triage rules
- Name the platform and storefront first. A Steam report and a Game Pass report can look similar but have different causes.
- Separate access, crash, performance, co-op, and reward issues. Mixing them creates unreliable workarounds.
- Treat one-off Discord or Steam comments as leads until the same pattern repeats across several players.
- Move a report from community reports to known issues only when the symptom, platform, and workaround are specific enough.
Need to report a bug?
Use the bug report guide to format platform, build, reproduction steps, expected behavior, actual behavior, and source context. A clean report is easier for other players to compare and easier for support teams to act on.
