I've gotten into GregTech recently on my FTB Ultimate (MC 1.4.7) world. After finally getting around to making an Alloy Smelter and hooking it into my AE system and powering it... it doesn't seem to want to work to make Invar. I do have custom configs, so it may be attributed to that. I looked into its recipes to see if what I want to craft is craftable. It is, but for some reason the maxEnergy in the recipe is halved from what I expected. How am I supposed to get as low as 16EU/t into the thing? More accurately, how do I get my Alloy Smelter to use 32EU/t like it's supposed to? Is there a config for it I'm missing?
