Iron Golem Spam

Hello together,

in the Village I built with about 50-60 villagers, I have a problem with the spawning rate of iron golems. There spawn so many of them, after a while all the mobs getting lags due to the ressource consumption of the golems. I haven´t counted them, but there are about as many golems as villagers in this area.

Could you please check the spawing algorithm for the golems?
If you want, I can also send you the world data. Thanks!

Best regards
Adrian Dengel
