[ 3:56]chrism3141: I’m playing 2 ladder games that I challenged other players. I can’t challenge a third person because it says I’m playing 3 games when I’m only playing 2. Can this be fixed?

It appears that this null game situation can still occur. In the Site 13x13 Ladder, the top player balthahar has an outgoing challenge to BEKO8 (who is no longer in the ladder and has a ladder position of -1) which results in a null game page when clicked. Maybe this will help track down the issue.

I only recently discovered this because the JSON for the 13x13 ladder failed to parse because of this null game ID, which I didn’t know was possible to be null. I’ve since rectified that in The Conquest of Go to be able to display the list of players correctly by allowing it to be nullable.
