When villagers sleep in beds I noticed some issues.

While playing Minecraft survival mode I noticed some interesting bugs with villagers, When villagers sleep at night they seem to warp into to walls and go invisible. This only seems to happen when there is contact by anther villager or player. I noticed if you where to break the bed where they where sleeping in they will reappear. This issue seems to be affecting all game modes and can be really annoying while creating a village.
