I have built an iron farm, and it worked just fine, bit then the new hotfix came out. At first, everything was fine, but then iron golems started spawning on both slabs and leaves and glass. Then they stopped spawning all together. I killed all of the cats and still nothing. So I spent a couple of hours making another farm. I got 20 villagers, 20 beds, 20 works stations, and a bell. And yet not even a cat spawned. I then went back for a couple of hours and came back to find that nothing had spawned. This was done in a survival world without cheats, please help. resource starved player
