Couldn't tell you exactly what's going on, but the game crashes whenever the day starts and the pawns start going about their day. I noticed that some of the queued construction - specifically stairs - was marked as having insufficient resources, which is wrong. I assume it had a faulty path to resources.
Things I did differently in this game:
- Much heavier investment in heat control to produce bristle plant things
- Heavy use of insulated tiles
- Regular food shortages
The crash .dmp is attached, so is the output log. Anything else I should do? I could track down the save file if needed.
I'm afraid I can't point out the specific issue. The crash occurs on day start, including loading from autosave.
