As someone mentioned, when a game splits, whoever finishes their game first gets their game's stats recorded. Given that you said the timeout box came up a few times prior, it was someone's connection. Either:
1. Your connection "lagged out", was congested upstream, or something else, and you simply disconnected from them both, leaving you in your own game, OR
2. One of the UBs disconnected, then the bug occured that splits the game in two.
You have that information based on what you saw in the "countdown box". If they both had a counter and under "ejected by" was just you, then it's your connection. Given that you said you'd rather believe something else because you'd feel better, I don't expect you'll "remember" correctly. That attitude is despicable.
