Wow! I've never tried to stack domes before, I always just assumed that only one dome of each type could exist on a province. How do you see your active domes in the province? With 3 different domes, four sites, a temple lab & castle, it runs out of display space. Do you get a seperate icon for each air dome?
EXPLOIT, EXPLOIT!!!11!1!! Sorry, that's a joke, at least the additional emphasis is.
But it might not be WAD.
