Why cant I upgrade armor in the forge I make in CK? same armor can, only diffrens is I change name and ID on it. Any idea why?

You must create two recipes, one for being able to create it at the forge and the second for being able to improve it at the bench in the "constructible objects" (don't remember the exact name, sorry) list in the CK.

Ah yeah found it, thanks for the help!
