I will do my best to explain this glitch. My world was created in 1.8. I found a village but over time all of the villagers were killed off by zombies etc. I recently tried to fix the village by curing a zombie villager and putting the cured villager in my village. After a few days, it found out how to react near a wheat farm and it found a house to hide it at night. however, once it goes in the house it "struggles" to get out. It attempts to get out by opening the door, but it closes the door again. I just constantly stands near the door and repeats that here and there. It can only get out if I break the door down or help him somehow. Maybe because the game engine recognizes the place as a village, but the cured villager does not recognize the village much? Please fix their AI so they know how to leave their own houses, thanks.
