Started pioneer bo1 queue, had to cancel briefly for irl reasons upon hitting cancel it returns to home screen as is normal, but when I re-queue it immediately loads me into a match on my 2nd turn. So the server put me in a game while my client believed I was not. Most likely this is a desync cause by the game finding a match at the same moment I try to cancel it which is not a huge deal on match queue but could be pretty serious in an event queue.
