Make Angel's smelting recipes the best way by disabling direct ore smelting in furnaces. It forces you to go in the advanced metallurgy path. Need angel's smelting.
Small changes concerning balance, gameplay, or graphics.
Any interest in popping over the bronze, brass and invar alloys from ingots?
This is an idea, I will see if this is possible.
I asked Arch666Angel and he will add them soon, so I will just block bob's recipes after his upgrade.
