Villagers appear to sleep on the ground at random places around their beds, sometimes even in half blocks or through them (seems to be as far as ~16 blocks). I cannot interact with them. If I find the bed they should be sleeping at and break it, they will show up besides where the bed was, then I can put the bed back and all is fine. This happens are random, and by that I mean not the same villagers on each night. Some nights everyone is on their proper places.

Seems like a visual glitch since appears that it is only a matter of them displaying in the wrong place.
