For some reason in Regrowth 1.7.10, I can only break blocks with the effective tool listed in NEI. It won't allow me to do things like punch wood or sand, or even though my mattock is considered a shovel, I can't break sand blocks with it. If I want to remove items from a drawer, I have to do it with an axe in my hand. A whole bunch of things like that. Does anyone know what's going on? What can I do to fix it?
