The Artificial intelligence NEEDS to be improved. On my world, when its night time, the villagers have troubles to get in their beds. Instead of the villager to go through the Door of the house, they go on the wall where the bed is located. So the villagers ODVIOUSLY couldnt never get to their beds like that. The problems is that The villagers' Pathfinding is broken. The mobs doesnt know how to get where they want to go. This is a problem with ALL the mobs I think.

The Iron Golems are other story. The prefer to go pretty FAR from the village. So if is there a raid or a zombie invasion, I had to take care of it by myself. Also, at some point that the Iron Golems teleports. Like on a Village,  The Iron Golem was walking thorugh the village. And at on other day I found it on an animal pen. At some points I EVEN found it in a building. EXTREMELY weird and nonsense
