NoSuchFieldException: tabToDisplayOn
squeek502 opened this issue ยท 3 comments
Item.tabToDisplayOn doesn't exist when the MInecraft code is obfuscated. I'm too unfamiliar with reflection to know what the best way to fix this is, however, I see that there is an ObfuscationReflectionHelper and ReflectionHelper in FML which I assume would be useful in this case (though I don't know exactly how to use them).

Here's my attempt at a fix, unsure if it's the best method, but it seems to work: squeek502@8aa1eca
Fixed with a2e9cfe.
