I'm trying to make an iron farm on my survival world but nothing seems to be working. I have 21 beds per the requirements that I've been able to find online. I also have more than the 10 required villagers. they are all synced with work stations and are all synced with their beds as well. No iron golems or even cats are spawning. I get plenty of salmon and bones, even the occasional ink sac but no golems or cats. Any Ideas what I need to adjust?
