When you have the FutureMC dyes disabled, JEI still (somehow) detects the dyes and attempts to register them in recipes. Just load FutureMC with the dyes disabled and JEI will attempt to register the dyes that aren't actually enabled, resulting in a tooltip error showing because of the ore dictionary entry that the dyes have 'dyeColor.' All four dyes (black, brown, blue, white) cause this tooltip error and are attempted to still be registered by JEI.

(You could perhaps keep an eye out to see if this happens with other items in your mod with ore dictionary entries, such as the flowers and if disabling them causes them to appear in a recipe as a 'tooltip error' that uses the 'plant' ore dictionary entry in its recipe, etc.)

Ohhh okay. So because it shows in the OreDictionary, it messes up. Easy fix though, I'll get it out next update.

Fixed in 0.1.11
