NuclearCraft 2.x for version 1.12.2 is no longer being developed as the focus of attention has been shifted to the overhaul. Bugs reports will be responded to, but new features will no longer be accepted! Hopefully you can understand that working on two branches of this project at once is far too time-consuming!
