I've noticed there is a glitch in the final level that is interfering with the villagers' pathfinding. Unfortunately, I didn't see this until after the GMTK deadline but I will fix it in the future.
Not sure if this is the same bug you recently addressed, but I noticed on the last section that for whatever reason, 2 of the villagers seemed to just be absent. I was wondering if the game glitched them out of existence before they could perish, but after waiting for a while, I noticed that one of them rose out of the ground in the bottom-right corner of the screen. Which led me to think that maybe those two had clipped through the floor at some point, and miraculously floated back up.
Regardless, this was pretty fun. Died immediately when I had to traverse back through the cave myself. But, that's karma I guess!
