Could mod don't register its own copper for MC 1.18.2?
it is already in the game in it.

its still in there to not break the item/block registry. spawning of the ore can be deactivated in the configs and the blocks shoiuld drop vanilla raw copper. via tags the copper tingot is fully compatible with vanilla.

It is I just ask is it possible to make it don't register it only for the 1.18.2

that would break all existtng worls as the registrieswould no longer match. what is the exact issue you are facing ?

My question is rather caused looking at Create that had only left textures for 1.18.2 version of mod
