Seriously?

My first thought was have you logged in to origin on your phone, but I think you answered that. I do recall something a year or so ago where before an update anyone who was playing without logging in to origin was told by ea to log in to origin and synch their game or it would be lost after the update. If you played your game without logging in to origin when you started it's likely gone when you started again. If this is the case and you have receipts, check your country's consumer laws if you have trouble as they will owe you the donuts if it's their fault the springfield is gone. Have you tried opening it on your old phone or did you get rid of it? Were you using a different origin login when you played previously?
