In the attached video link, you can see that the first few villagers are able to pathfind to the beds facing the sides of the room. However, later in the clip once the beds are moved to the back, any villager not directly in front of the door will try to move to the beds through the back wall. This gets them stuck in a loop constantly getting mad because they think they can't make it to the beds. On our realm, we had similar issues where villagers would walk into walls even if facing directly at a door, but I was unable to replicate this here.
