So that bug where you get another queue pop (Accept, Deny, Dismiss) while in the map select screen for an already popped queue seems to be back.
I just had this happen, and confirmed with the other people in my game.
I don’t think anybody was locked out of our match because of this, but just a head up that this bug is back.
Perhaps don’t accept the 2nd queue if this happens to you, as last time it was around, people who did got put into a different game and the others were stuck with less than a 5v5.
