iOS version is a piece of crap. Got a iPad 4 and it can’t save a game. I have deleted the app and put it back on over 10 times, closed all programmes, tried everything and everytime I save a game and then try and load said game, the game crashes. Piece of crap cost me 45RMB as well.
Having email support integrated a into the start menu was probably a give way that all is not well with this current version. Hope they update it and sort this issue out.
