it's not, Jar. I've tested in older versions of MC (Ex: 1.2.5, 1.4.7) and this effect is not present.
I'm thinking it's something with DXtory
Happened to me too, but my whole Computer crashed instead.
Thank you.
I noticed this too. I think Mob And Monter are just replacement mobs to start building off of when someone starts to make a mod. A Spawner called 'Monter Spawner' Is obtainable Via MCedit, but it wont do anything. Considering its trying to spawn an Invalid entity.
I forgot, what block is block ID 144?
This Is Very Intresting.
This is because of Mojang removing numerical item IDs. Try /give @p command_block
