So Ive been having this weird bug: Whenever I kill creepers I get diamond drawplates

I'm using ProjectRed V 4.3.5.30, any help is appreciated!

These are the exact Item's that it drops: http://gyazo.com/1c778a84076c3f37324c655d7b094e67

It's an id thing. Fix your config.

How? What config do I use? gunpowder and drawplate's ID's are different.....
