In Civ. 4, we used to be able to see which tiles a city was working by looking for the little huts. However, in Civ. 5 there doesn't seem to be any indication as to which tiles a city is working without going into City view. I do notice that there seems to be a hut on tiles with improvements when they are being worked, but I don't see a hut on tiles with no improvements that are being worked by a city. Is this the case, or is there something I'm missing?
