I was trying to build an iron hatchet today, but suddenly I noticed I couldn't make any part with iron! Any other material like cobblestone or wood works, but not Iron. It just doesn't show anything on the right.
I think it has something to do with the new Hexxit Update. A few days ago I had made an iron Mattock, but after updating yesterday I can't. You can actually see the mattock there in the hotbar.
Am I the only one? Is it a bug? How do I fix it?
