I imagine this is a more general issue than just this item, though--I will check if any more custom items have similar results and append this issue.

Recipe to make an MI Quantum Helmet, the mold being an ingredient:

Crafting tree for the Quantum Helmet:

A crafting tree for the mold itself does work fine:

It's been pointed out to me this is likely because the mold item is not consumed in the making of the quantum armor piece.

If that's the case, I'll close this and file a different issue... I'd consider that a misfeature or bug, since it hides the true, full crafting tree to make an item that includes an unconsumed ingredient.

This is due to MI's implementation. EMI lets recipes have ingredients that return themselves like molds that could show in the tree, but MI chooses to not list it as an ingredient.

Thank you for clarifying; will take this up with MI then.

Cheers, and always, thanks for EMI.
It has been a part of many hours of MC fun for me.
