Hey all!
I notice a strange behaviour with the Ultradense furnace with rare earth smelting (didn't try on another recipe).
Sometimes, 500 materials from input will disappear without smelting, and sometimes there will be smelting using zero input. I don't think there is loss of ore here, but it definitely goes places that aren't accessible to mere mortals. Weird.
Also, since the mod doesn't use coal, the big rocks that give coal shouldn't.
Cheers!
