Description of the Bug
... Chiseled Copper Blocks do not break faster with a pickaxe and never drop themselves.

Steps to Reproduce
... Place any of the rechiseled copper block variants and break them

Screenshots

Looking at the code, copper variants seem to have a unique definition as opposed to pulling from the vanilla block

That is intentional as Create's oxidation stuff causes a crash when the copper block is loaded early.

I added the copper blocks to the appropriate tags now in Rechiseled version 1.0.4a, so it should all be mineable now.
Thank you for reporting the issue!
