If you navigate to its corresponding tournament page, you won’t be able to find the game: https://online-go.com/tournament/30837. The tournament did progress to the 2nd round and created new games, but the tournament page was lagged.
You’re right. I can confirm what you described. The circled number is 7 for me now, but I do have 8 games waiting for my move. But this issue is NOT the same one as I described in my post.
