Well, Ranked Duels NMPZ, Rating like 900, my website bugged a little, as always, my guess doesn't react (may be due to internet), so I pressed F5 to reload the tab and rejoin my duels game, but it just sent me into the matchmaking, instantly finding a new match, while the other one is still going. I looked at the breakdown, there was a last round I never saw and couldn't rejoin, so I lost.
