Postgame Carnage Report Doesn't Always Display

Whenever I finish a game of any type, there’s maybe a 10 or 20 percent chance that the game will show a spinning wheel and say something like, “retrieving postgame stats” for a while and then say it’s unable to retrieve them. This guy seems to be having even worse problems:

I have reset my router and xbox, and my connection is fine because it says it is and because the actual game play is fine. I really love the game so far and would love some info about this problem. Thanks.
