Oh, you'll enjoy this... Tournament rankings.

@Mark_MiwurdzI kind of assumed that this might have been the exact reason to start a new season.  They chose an odd time for it, but with the game re-starting at season 1, it might reset the online scoring system so that wins are worth 5 points again.  I agree with you that if the game had stayed in season 12 forever, the online rankings would basically be frozen until servers shut down.  I haven't tested this myself so I can't confirm if today's glitch has reset the scoring or not for online modes.. I just don't understand why they didn't just create a season 13. Why call it season 1 and overwrite all of the previous stats? This has to be some kind of huge oversight as it doesn't make sense to essentially erase people's history and progress.
