The last 3-4 days I am finding that when someone disconnects from a multi-player match play game, the game freezes and does not allow me to continue. I can't say with 100% certainty, but I think it might be happening when there are 2 players, and 1 drops, leaving me alone to finish by myself.
I will post more details as it happens in the future and start paying closer attention to the scenario causing it.
