spawn 1 zombies at location of event-entity with nbt from"{PersistenceRequired:true,isBaby:0b}"
cancel event
I am trying to replace every mob that spawns by a non-baby zombie that doesn't despawn. What is wrong with this piece of code? It crashes my server for some reason, without the nbt it works fine. (srry, can't get the code block to work, am new to it)
