In my survival world I made a pretty big village, and I brought over 6 villagers from an NPC village. They wander through the village and treat it as if it was spawned in, and that's not the problem. They reproduce, spawn Iron Golems, and act completely normal. Except at night. All 20 or so of them try to cram into the same 3 or 4 buildings every night, and I was wondering why. Any explanations?
Odd villager behavior?
