Short description:

this bug allows people to duplicate variable cards via the data cloning feature

Steps to reproduce the problem:

1. take a couple of unformatted data cards and 1 assigned
2. take 1 unformatted and one assigned card and put them in together as if to copy the data
   3.drop the rest of the unformatted cards onto the one in the crafting table
   4.finish the crafting recipe
   5.the cards in the crafting table will increase

Expected behaviour:

it seems the copy mechanic can be used to copy cards instead of data
