Lo-Fi Games

So for my first foray into the editor I decided to change up a recipe for the Plate Beating Station. It annoyed me that it was raw iron. So I edited the "plates" functionality in buildings->functionality


This causes strange behaviour. The Iron plates are not "consumed" and you can basically use the station for free.
Am I missing something?

This seemed like a simple swap to me. I've tried reimporting my game but it doesn't make any difference. My "Mod" just breaks plate beating stations so that they need no input

Any help is appreciated.
Thanks

Look for armor plate under the items category, you will have to change it's ingredients to iron plates.
