According to King Lemming on the COFH Discord, the correct way to handle recipes for the induction smelter that use multiple of a single item is to swap the order of ingredients.
Not swapping the order will simply result in the recipe not being removed, but no error being raised. I first though to generate an error saying to swap the order of inputs in ZenScript, but then it seemed obvious just to try calling removeRecipe a second time.
