Actual Behavior

Grip materials duplicate when a tool with a preexisting grip is passed through the crafting slot and output slot.

Steps to Reproduce the Problem

1. Take a tool
2. Give the tool a grip
3. Fill the 2x2 Inventory Crafting Grid with 6 of the same grip material in stacks of 2 (So, 3 slots are filled with 1 slot open)
4. Move the tool between the output slot and the open crafting grid slot
5. The materials in the 3 filled slots begin duplicating each time the tool is moved between the slots
6. The duplicated materials can then be removed

Additional

I've never sent in a bug report before so I'm sorry if I did something wrong or if this bug has already been addressed before, I couldn't find it when searching around. It seems like it only applies to Grips and not main tool parts.
