Title: Fixing CreatureSpawnEvent error

Developer comment (@matejdro):

> Error is about Rebelance Villagers scanning for possible mate and while it is still scanning it also tries to delete one villager which of course do not work.

This fixed the issue, villagers are mating properly, no errors show up.
