I know the game has always been a bit iffy on completely surrounding your base in walls with pathfinding, but in all my years of playing I haven't ever had it crash. Plus some of the walls around my base are natural (I'm north of Clownsteady, and a bit southeast of the Workshop complex that's NW of clownsteady. A dead zone).
Since it's an unhandled exception there's no crash dump to upload either.
I'd upload my save but the file is apparently too large (32 mb). If you guys need it either reply to this post with how you'd like me to send it or message me on steam - my UN and profile URL is the same as my lofigames UN - I'll respond a bit sooner on steam since I'm continuously online on it
Also, I have the quick loading or whatever on (the one that loads multiple characters areas simultaneously when they're far apart)... So I don't know how stable that is. The game is running fine/no different from how it usually does.
ALSO, I'm on a HDD and not an SSD - but again that shouldn't have anything to do with the unhandled exception but I know someone is going to ask because it makes a huge difference in Kenshi (I just haven't plugged mine in yet
