mine stops at 70%... this happened after i started selling buildings and moving them around very quickly... The game then gave this error for the first time, "Could not establish phone connection" smth like that, then it loaded the game normally after a browser restart, then i continued arranging my buildings and ban it gave an error again, second time i was kicked from the game by the error and now it only loads till 70% (that is about World 2), World1 works fine though.
