BLUF: When host migration fails, create a private instance on each user's xbox and migrate the game to there, then immediately end the match. It should still preserve the accomplishment and efforts put forth without overtaxing the server or the matching service.

I find it infuriating when I take time out of my day to relax and play a game, only to find that the 5-10 minutes I've spent in a match earning kills and levelling up my weapons counts for naught because of a faulty migration effort. I propose that when host migration fails, the gamestate is dumped to the user's private instance, and then exited as normal, preserving K/D ratio and stats.
