Not sure why there is a Blacksmith and a Smelter when they both do the same thing and apparently both add 50% to mining.

Also The Mint of Ruvina (spelling?) does not add up correctly. If it's supposed to boost you 100% then why do i go from 22 gold per turn to spprox 36 gold per turn? Shouldn't it double it since, current gold income of 22 x 1.0 = 22 + current gold income = 44??? Not sure if this being added to gold mines and anyone generating gold per turn in my entourage, I gather it's not though I think it should be if guys are stationed at that city or gold from the mines are going to that city.

Not sure if this is a bug or some wierd design thing that I'm missing.
