i did finish gold rookie, talent, pro and champion with all gold on iOS 4.0.1 (no gamecenter). after that i switched to 5.0.1 and finished gold in elite. on gamecenter i can only see the gold in elite but no achiements for the cars i got in rookie, talent, pro and champion. i did also try to re-win all the again without success. is there any way to get this achievents again in gamecenter?
