Issue Description:

I am currently working on a modpack myself and tried the function of using an stack of items in a recipe rather than just a single one (f.e. 2 furnaces in a recipe input slot instead of the usual 1) as I heared that this is recently possible. (attached a screenshot which proves that JEI noticed the recipe as valid as well)

What happens:

In the process of crafting the Generator the recipe only consumed 1 Furnace instead of both.

What you expected to happen:

The recipe should've taken away both furnaces in the process.

Stacked crafting isn't supported by vanilla, I'm not sure where you heard that it was possible...

I heared it from a different mod author. And since the recipe technically only works if 2 furnaces are present (but only consumes 1 of them) I assumed that it's a bug.

But if you say that it is impossible to make that work I guess I won't touch that again.

Note: The mod author (who btw has working stacked crafting in his mod) was Speiger (IC2 Classics). He said it's not used in vanilla, yet technically possible. So I assumed that CraftTweaker supported it.
