I saw that there were many new levels available today and started building many of them (about 10 residential, and 3 each of food/service/retail/recreation.) The screen then became somewhat odd - the menu button was missing at the bottom of the screen and the bottom status info about how many coins and bux remain wasn't there, rather just a transparent section. Then the game crashed and I haven't been able to get it to start again- it crashes upon launch. Over and over. I tried the usual things (launch the game in airplane mode, kill the app and try again) numerous times without success. This is under iOS 6.
Has anyone else had this problem and been able to resolve it? It's presently unlaunchable and thus unplayable.
