Villagers only recognize beds and workstations at random times. Villagers will ignore them and wander aimlessly until without anything changing they suddenly will recognize them and interact with them properly. Then again at random intervals they all go back to ignoring them. No particles to show that they cannot reach them or the bed is obstructed, just ignoring completely. Discovered it on a dedicated server, tested in creative on the same seed and it worked perfectly, then switched back to the server and still only works at bursts. All villagers have the same problem at the same time, all villagers both ignore and recognize at the same time.
