Things i have noticed about the game that might explain whats going on. For starters, if you simply turn off your xbox at the end of a match (lets say to get off for the night after a loss with a bad team), the next time you get back on the game you will sometimes see the match results on the screen. If you do the same thing anywhere else (tower or any destination) you will be met with a viper error when you get back in the game and nothing else. If you quit the game through the xbox menu however, you dont get either of these issues. My thoughts is that the issue is with how the game quits. Something about it simply isnt actually quitting (be it some protocol in the code).
