A new internal version of the game is now available that fixes a few smaller bugs, the main one being players sometimes having issues saving the game. This should now be fixed! It will not affect current save games, but should work with future ones. Note that this issue was related to Steam not always saving the fact that a game had already been installed previously, not anything to do with the game's actual code. A few small adjustments in income from various activities and a small bug that rarely made income not calculated with the various street properties correctly are included too. Thanks and enjoy!
