You know what, Rimworld is actually dogshit.

The pathfinding in it is literally broken, and the AI will on purpose do the most destructive actions just to spite you. Not the narrative one, your own pawns will, you can tear down a house, specify remove the roof first, and then the walls, and the pawns will still at one point remove the walls while the roof is still intact which then falls on them and dismembers one of their appendages. This game sucks.
