I made a villager breeder (on peaceful btw), its a fenced in area so they cant escape. So yesterday my farmer villager went missing while i was alt tabbed watching yt. Like it completely disappeared. Then a couple minutes ago i came back from being afk and the fence was broken in a spot and all my villagers escaped? I was at my desk the entire time so i dont have any clue what could have happened, but i figured id ask you guys to see if anyone might have an explanation. I joined minecraft like a week ago after about 4 years not playing so i dont know whether there are new villager mechanics that could explain this?
