The stairs up to the front door of the cartographer's building in desert villages will cause any villager trying to access the cartography table inside to get stuck on the stairs and will try attempt to jump over the slab which is on the second floor, even though the height of the wall they try to jump over is 1.5 blocks high. - They seem to ignore that there is a slab there and will endlessly jump there until their schedule is updated. - The pathfinding is just a little weird, since they completely ignore the doorway into the building.
