Villagers no longer pathfind to beds, and occasionally doors, and some job blocks. 

At night, rather than finding a door and bed, they stand outside facing a wall, often the wall closest to the bed. Alternatively, they run around until daytime. This means most villagers die if "peaceful" mode is not on, as they do not find their ways indoors more often than not. 

Job blocks can have similar issues - if the block is inside a building, they don't seem to be able to pathfind to the door or empty space where one would be. 

This has been ongoing for an extended time, as well.
