When the mod is enabled, you start out with an Furnace.
However this Furnace does not accept anything as fuel. The Error states Stone Furnace can't be used as fuel for Coal (or Wood or whatever) so it almost seems as if the mod has the fuel and furnace mixed up... I've checked but this does not happen in the base 0.18.11
Also the copper colored ore is Iron ore and the Iron ore is called copper ore... (you gain the ore that is mentioned by the tooltip, but still it's confusing :) )
