I have created a large village with 100+ villagers and beds. Villagers are leaving the confines of the village and head to the NW of the village and idle there. There are hundreds of them. Iron golems are with them as well. Seems to be an issue with their AI. I have noticed this with my other large village. They all gather in the NW and then idle around day and night. They never leave the area and are accumulating. This is creating massive lag anytime I go near the area.
