      Description

      There is a very critical bug, where if a spawner is placed on a server it will create MASSIVE log files on the other players computer (15GB+) How to reproduce: Start a minecraft server, log in, type this command: 

      /give @p spawner{BlockEntityTag:{SpawnData:

      {id:"minecraft:iron_golem"}

      ,SpawnPotentials:\\{Weight:1,Entity:{id:"minecraft:iron_golem"}}}} 1

      Place the spawner, go to your %appdata& > .minecraft > logs and you will get extremely large error logs with this error being spammed so bad that it can rack up in the gigabytes in minutes:
