Is any one else bugged by the extreme lack of furnaces anywhere? There should be one in just about every blacksmith since its kinda a required tool of the trade. I can justify some not having one because they'd probably buy ingots to do their work instead of the ore. But still, only three cities? Come on Bethesda.
The mines themselves usually have them, there's no point for a blacksmith to have a furnace if the mines where the ore is mined already turn the stuff into ingots.
