Note: For the first few hours, I had the map editor update sitting where the game update was supposed to be. So if you download the game patch in the first few hours of September 7, 2011, just download it again. The actual game patch is in place now (not the map editor patch).
This update brings a number of bug fixes and some features you might find interesting. Read more about them here:
