Just got an error now after a bunch of matches. I wonder if it has anything to do with me PMing people outside the game while the match was going on. 2 people got kicked, the other 2 didn’t. I was leader by the way if that matters.
I bring that up, because in case you’re not aware, if you use the in-game chat while a party is going on, it will often kick you out of the match. You’ll still be in the party, but you’ll have to wait till everyone is finished before you can join again.
