Problems with Game Center

Mantiz_Developers

Hello I have a problem when I try to use the Game Center behaviors. I have already set up the achievements in the itunes connect page and put the game center behaviors in my game. The problem comes when I test them in the compiled version in my iphone, actually everything its ok but sometimes when an achievement is accomplished the notification of game center is shown a lot of times, it appears the first time and then goes and one second after appears again, this problem also occurs in a different way when I preview the game in the GameSalad Creator, when I pass a level of the game sometimes, the notification that the achievment would be updated appears but the achievement it refers has not been accomplished (i've checked it and its always the last achievement of my list, for example if I my las achievement is the achievement 23 when I pass a level it appears the notification that says that achievement was accomplished but that is not true and if I add an achievement 24 and the test the level appears the notification that says that achievement was accomplished but it is not) I've checked al my rules that include the update achievement behavior and they are correct but this problem still happens when I pass that to the iphone it happens the same and also in the iphone the notification appears repeatedly several times

I have another question, is there anyway I can know in the game that the player has logged in successfully to game center? This because I have checked that if the user is not loggedIn in game salad and accomplishes some achievements when he logIn game center this achievements will not be updated and he will lose the opportunity of get them again so if there would be a way to know if the user is not loggedIn Game Center I could put in the rule to updateAchievements to check that.

Thanks!
