This bug happened only 2 times so far. The first time 8 days ago, when I reported the bug, and after 28 games, yesterday it happened again. I don't know if this is related, but one of my friends had a bad internet connection, and kept disconnecting. After the game ended (we surrendered, but I don't think it matters) we saw the "don't wait for statistics" message. We disbanded the lobby and we created a new one. We could not start the queue because an error message kept popping up when the leader of the group pressed "find match". We all experienced this bug once, so we simply decided not to play anymore for the rest of the evening.
Unfortunately I don't remember the error message (also I have the client in italian). I was kinda upset because we couldn't play anymore.Even if i have no proof, I think this bug affects all 10 people involved in the game.
I hope this message will be helpful! <3
Really appreciate the details! It definitely gives me a few leads :)
