My villagers seem to be trying to get to their home points, but instead of pathing through the door, they get stuck in exterior corners. (I'm in the crystal ball's village, and these are all original doors.) Judging from the drop in my population, I suspect they're often suffocating there too.

On closer examination, I am also seeing them getting stuck in interior corners. I believe they are trying to path through diagonally-adjacent columns of blocks, despite that they can't actually get through those.
