I while back, Surge fixed the hostile mob spawns. When he did that, something broke that caused docile mobs to not breed and iron farms to not work. He fixed that and it caused the hostile mob spawn rates to sky rocket. Now, he fixed the hostile mob problems again, and now animals don't breed and iron farms no longer work again. Also, I'm having more server lag than I had when you could build up thousands of mobs. I don't know if that's on my side but I figured I should add that in here. Added: I just tried to make a snow golem and they don't spawn again Villagers despawn no matter how many are in a small area
