Sometimes I would see villagers getting stuck when they are trying to go to their work station or to their bed. When a butcher tries to get to their smoker, they would be stuck on the smooth stone slab thing and eventually lose their job because it thinks it can't get to the smoker even though it can, as shown in one of the pictures. One of the butchers is stuck outside the butcher shop because they cant seem to walk around the building to get to their work station. Cartographers and masons sometimes get stuck on the trapdoors at their work buildings. I even noticed the armorer somehow forgot his job. A lot of pathfinding issues with houses happen with the 4-bed house. a villager who sleeps at the upper-right bed jumps up and down on the stairs because it cant figure out how to walk up the stairs. Finally, a villager who sleeps in the house with a green carpet gets stuck on the carpet and can't walk around, as shown in another picture. I've also noticed villagers who try to sleep in a bed that was claimed by another villager.
