I've created a new pickaxe in the CK; however, it tells me that I need a pickaxe when I try to mine an ore node. The problem only seems to occur with new pickaxes that I've created, and not the generic pickaxe or notched pickaxe (both of those work fine). Even if I create an exact duplicate of the generic pickaxe, with nothing else changed except for the ID and name, it still won't mine an ore node.
Is there any fix to this? I tried looking to see if a pickaxe has a special script or code that allows it to mine, but I couldn't find anything.
