I have a feeling there’s a way to force out-of-sync in game. More than once I’ve been on a side clearly winning, and then the game just suddenly goes out of sync and drops me from the game. The strangest part is that most of the time, the game has been running smoothly before quickly crashing.
It doesn’t matter now, since losing does not actually count anywhere, but I hope it gets looked into once the devs come up with built-in elo.
