Issue
If you do a blank cast in the smeltery you get aluminum brass out. (Blank Cast can be made with 2 gold in the smeltery, which actually costs 1 copper and 3 tin in the Induction Smelter or Arc Furnace).

I know, that is intentional, converting gold to aluminum brass isn't particularly strong :)

• but thanks for the report!
