I am trying to add sim number 12. I have started building the house which has now been building for 3 days! Every time I click on the 'new' house the game exits and I return to my I phone 4 s home screen I have saved data. Uninstalled and reinstalled game but still having same problem. If I click to try and add sim in a different house it says not so fast I have to complete adding the other sim first. Which I can't!! HELP ME PLEASE!!
