I have an iPhone 5s. I live in USA. I switched my App Store to Canada to get the game then I switched back to USA App Store. I am connected to Gamecenter but I dont see Doninations in my games. I have bought gems once. I am getting ready to get an I phone six and I want to make sure I can keep my current base. Is there anything special I need to do? Im worried that since the game does not display in Game Center it wont recognize me on my new phone. Please help. Thank you.
