Issue description:

Items that are supposed to be reused instead of consumed are doubled when the actual recipe is crafted in RS's Crafting Grid.

What happens:

I've added a new recipe with Craft Tweaker like this:
recipes.addShaped(<woot:skull:0>, [[<woot:yahhammer>.reuse(), <minecraft:iron_block>, null], [<ore:itemSkull>, <woot:dye:4>.reuse(), <ore:itemSkull>], [null, <minecraft:obsidian:*>.reuse(), null]]);
.reuse() indicates that the item is not consumed but given back after crafting.
Using the recipe in a regular crafting bench has the expected result of the items with the .reuse() function not being consumed.
Using the same recipe in the Crafting Grid will produce the result of the recipe but also doubles the items with the .reuse() function (in my example the woot:yahhammer and minecraft:obsidian:*

What you expected to happen:

RS supports items that stay in the crafting grid, maybe this is a Craft Tweaker issue.

Does this bug happen with a normal crafting table as well?

It works on vanilla and modded tables just fine.

This is a Craft Tweaker problem. RS handles remaining items properly.
