So yesterday (03.11.2012) i play for like 3 hours, got marathon pro and some couple of lvls i dont remember how many maybe 3-4. Again yesterday night i got in to game for 20 mins and saw that all my gained lvls + marathon pro was gone and set back to a point before that "3 hours". Nevertheless i palyed the game for 30 mins and again got a lvl.

 

Now (04.11.2012) i got in to game again and my gained lvl is gone again and set back to the point beforehand of that "3 hours" i played.

 

What is the reason for this? Is it going to happen whenever i play? Clearly my user data is not registered to the server and not updated so the game calls for previous data (probs a backup save?). Is it going to happen whenever i play?

You messed with your stats, leaving them in a state that the server will reject them.

Having the spinning skull emblem unlocked or prestige 11 are common causes of it.

well i am lvl 30 and prestige 7 i suppose. I dont know if i have that emblem unlocked but how to fis this?

same problem here!!
