I've been going around a few villages that have been having children, but they aren't spawning an iron golem. Anyone else experiencing that?
Taken from the wiki, Also take note that iron golems do not spawn in town, as stated in the changelog.
Correct, soon villagers will also not spawn naturally in Town. People keep making giant villager spawners and causing problems for neighbors lag.
Could there also be a limit on animals? There are Res'es on some servers who have a whole underground cavern full or floors of their houses full and it lags :/
It is very difficult to place a limit on animals per res unless we were constantly looping through and checking all animals to see what res they are in, that would potentially cause even more load.
