Annoying display bug: if I hit "b" to go to the city's build screen/mode _more than just once_ or if i hit the "next turn" button while still in the city's build screen/mode then I get stuck in the "straight top down" view mode for the entire game indefinitely (even on cloth map, so zooming in/out doesn't end it, like entering/leaving build mode another time, too), the only way to get the isometric view back is saving the game and restarting the program, loading game...
