The iron farm dont work for anything, because even the villager are doing their own job when putting the block that they want to work. But it seems the lag comes and nothing has spawn like iron farm. But it only spawns cats . alot of cats but no iron golem spawns. And I did the same iron farm like Silentwisperer the minecraft youtuber pro. But i dont know why anything has spawn. I make the villagers breed. And all lag comes in that area. Please try to find out why is not working.
