Centrifuge Recipe Crash :/

Okay, this time, i'm getting a centrifuge crash - Apparently it's a 'ticking entity' here's the paste bin for the error: http://pastebin.com/EY0Zj7Zv

And here's the code that's causing the crash: http://pastebin.com/yYmKNFxt

Any chance anybody know a fix to my error?

Code

Recipes.centrifuge.addRecipe(new RecipeInputItemStack(new ItemStack(General.SapphireDust)), null, SapphireGemStone);

never use null in centrifuge Recipe ... set a heat level like 1000 instead null

Thanks for the info It says meta data so I thought it was the same as the add recipe (InputItem:metadata, output)
