Howdy, I'm playing Tekkit Legends 1.0.7 and found a bug in the IC Classic Iron Furnace. The Inputs for the top and bottom slots are reversed. To smelt ores you have to pipe them thru the bottom instead of being able to use a hopper on the top. Not an insurmountable issue, but annoying nonetheless. Just thought I'd post here in case anyone else was having troubles.
Very good mod altogether.
