Issue description:

Autocrafting can duplicate items

What happens:

When requesting n of a item to be autocrafted (crafting recipe), I can take more items out (most of the times 2n-2) items out of the rs system.

What you expected to happen:

When requesting n of a item to be autocrafted (crafting recipe), I expect to be able to get n items.

Steps to reproduce:

1. Setup simple autocrafting for crafting recipes
2. Request n items ( n > 1)
3. Try to take out n items from the RS system and see that you got more than that.

I can not reproduce this.

Did you have this bug with processing patterns on regular patterns?

And does it happen with every item or only a limited set of items that are requested?

It definitely happens with crafting patterns. I don't think I observed it with processing patterns.
It happens with all items 90% of the time I request something.

Also I think this is happening with items requested on crafting that have durability. For example:

Using actually additions you can use a knife with a seed in a crafting bench to make bio-mash, the more seeds you use the more durability it takes out of the knife.

When doing autocrafting, and making a crafting recipe such as "knife+seed = biomash" (regular pattern), it will always reuse the same knife, without taking durability from it.
