Hello everyone, I'm new to forge, and to this forum, I need some help with a mod of mine. I've been making a reverse crafting table mod, but there's a problem, it makes infinite items after the first uncraft. It's also on a per item basis, so if I uncraft 2 blue wool, the first will be fine, the second will be infinite and not real, also, they don't stack. So is it a sync issue between objects, or what? What causes this issue? If I need to supply code, just say so, but I don't think that's the problem. I've just copied and reversed some of the workbench code.
