If you have any ideas let me know in the comments.
There is one major flaw with this mod and its on Neo-forge 1.21.1, the issue is that you cannot mine stone with pickaxes normally, its slow and it wont drop. I've done research and i couldn't find anything about it. if you know the fix or created a seperate file i'd be happy :) for now tho avoid playing Neo-forge on your next survival world if your gonna use the mod :/
