Step one: check which build you are on
GRAIN ROT shipped seven patches in its first five days. A large share of what people are still describing as bugs was fixed between 8 and 12 August.
Before anything else, let Steam update the game and see whether the problem survives.

Stuck on a quest
The developers' pinned Launch FAQ gives a specific diagnostic:
"If you encounter quest or progression problems on an older save, please first check whether the problem also occurs on a fresh save."
That is aimed at demo and playtest saves, which "may still load, but they are not the recommended way to begin a full playthrough" — the release changed quests, balance and progression substantially.
Two quest blocks have known non-bug answers:
- Stuck after "The Big One" with Quill outside the bunker → you need to hand in the research at his apartment first. See Quill
- Stuck looking for the Corrupted Elite → it is behind a portal that can appear from level 5 down, not a fixed location. See Corrupted Elite
Cannot extract
Two different causes, and they need different answers:
- You are in a small body on a Fuse run. Small bodies cannot pick up a fuse, which has stranded whole groups who had the coins ready. Details and the workaround on extraction
- Enemies are camping the elevator. This is real and reported — the counters players use are on the same page
The third floor will not open
It is not a bug and there is no key. The developers' roadmap puts the Outpost's third floor in the October update. See 3rd floor.
The demo will not launch
The demo has been delisted. If it is still in your library from June, that is why it may not start or update. See demo.
How to report a bug so it gets fixed
The FAQ asks for a specific list, and reports that include it get triaged faster:
- What happened and what you expected to happen
- Steps that reproduce it
- Whether you were playing solo, hosting, or joining
- A screenshot or short video where possible
- The approximate time it occurred
- Logs or save files when requested by the support team
⚠️ The FAQ also asks: "Please do not publicly post Steam IDs, account credentials, or other private information."
Where to send it, per the FAQ: the official Discord, #🐛 Bug Report for bugs and
#open-tech-ticket for technical support. Channel access is granted through #roles.
What is not confirmed
- Whether any of the fixed issues have regressed. We have not retested them
- Steam Deck specifics — the developers say it runs smoothly in internal testing but the game is not Steam Deck Verified. See platforms
- Whether an in-game bug reporter exists — everything routes through Discord
