      Description

      It seems like mob spawners are crashing the game, cause the new attributes on the mobs.

      I created a standard mob spawner in mc edit. All works fine, but if i enter the world in minecraft, it crashes instantly.
      If i move the spawner away in an unloaded chunk minecraft works fine, until it´s trying to load the spawner. So it has to be the spawner i guess.
