Something happed with forge weapon today (or after crash?)
If I start forging a weapon from a mineral blank, lets say mithril, I will get a iron weapon of same type instead and still have to mineral blank in my inventory.

So if I start forging a long-sword from a mithril blank it will take me 1 minute and 40 sekonds and then I will have one iron long-sword and one mithril blank in my inventory. The mineral blank will now be locked to long-sword if I try to forge something else from it.
If I try forging a new long-sword I will get yet another iron with the blank still in my inventory.

If I have a iron blank, it will also still be there after forge.
If I have no blank at all it will just say I need a weapon blank to forge like usual.
