Crafting: Item that needs 2 of an item. Different grade ingredients do not work.
Example - Metal Weighted Ribbing (2x Copper Sheets)
In Inventory - Copper Sheet (Grade A) + Copper Sheet (Grade B)
When I attempt to craft it says a copper sheet is missing, on crafting screen. I can set up the table and get all the way to button presses for crafting and then it fails, item is missing.
