Issue Description:

I did a setup for autocrafting all alloy with a single alloy smelter. If i request more alloys at the same time like invar and bronze i allways get iron alloy ingots

What happens:

Iron Alloy ingots are created when requesting invar and bronze at the same time ( hardened upgrad kit from thermal)

What you expected to happen:

Smelting Invar and Bronze not Iron Alloy ingots

Steps to reproduce:

1.setup refined storage with autocrafting for Invar and Bronze in an alloy smelter
2.request hardened upgrade kit from thermal or anything else that needs 2 different alloy with on containing iron
3.

and what's your point?

You're outdated, the recipe for construction alloy was changed in .37

Use a separate alloy smelter for invar and other iron related alloys.
