Hey! I have been playing Simcity 2013 for almost a year now and have been really enjoying the game. There is this one annoying problem that has been bothering me for a while. I had a tourism city called Windy Town that was buying water from its neighbor, Shape City. We had no excess water, so the water number was at 0. Not a deficit and no extra water; perfect, right? Not! My water icon would be yellow even though I have just enough to run the city. Placing more water towers in Windy Town didn't work. Is this a bug, or do I have polluted water that it isn't telling me about?
