Villagers, when going to lay in their beds, will begin to rapidly slide away from their bed, and although they usually reappear after a few minutes in the morning, they have now begun to completely disappear. Their physical bodies are somewhere else so that we cannot interact with them, but they are still able to interact with things like doors and work stations, and particles are seen when they do so. We're only now experiencing this problem during the newest update of Bedrock, and we have just updated our world into a Realm.

Also: it is possible to push the villagers around on the beds.
