This isn't exactly game-breaking, but I'm having a problem with Casting Channels where they seem to select certain casting tables and only fill them half-way, dividing potential ingots among separate tables and preventing them from being cast. The average loss is 2 ingots (1 ore), which isn't too much but it's enough to be annoying. In addition, the half-filled casts prevent other metals from being cast. Anyone know of a fix / dealt with this issue before? Thanks! Oh yes and one more thing: I think that item casts should be redeemable for their gold/aluminum brass.
