This datapack disables crafting of copper tools/armor from:
- Mo' Shiz (ms)
- Create Stuff & Additions (create_sa)

It does NOT remove items from JEI or creative tabs (items still exist), but players cannot craft them in survival.
Vanilla Backport copper gear remains untouched.

Install:
- Server: put this zip in /world/datapacks/ then /reload
- OpenLoader: put in openloader/data/ as usual (zip is fine)

If you still obtain these items from loot/trades, tell me and I'll also override the relevant loot tables/trades.
