I made this iron farm and it was working great but I didn’t want to have to go all the way to the bottom to collect the iron. I made a bubble elevator to try to fix that and when I did it just stopped working. I see no reason why the iron golems stopped spawning. There aren’t any strays wandering around that are stopping the spawning. If anyone knows why this isn’t working please let me know!
