5. I randomly get weird UI glitches where the tile yields display on the map do not match the tile yields actually being produced. Example: in this screen shot, the map displays 3 Food 1 Gold on a farm tile that is actually producing only 3 Food.
I've caught this in the act actually, sometimes for some reason, some of my farms turn into 3(4) food 1 gold tiles for about one or two turns, after that they go back to their normal yields, but since the user interface have always blown at updating yields on the map, they stay 3(4) food 1 gold on the map for quite a while after. No idea why this occurs as of yet.
