although i have only 2 games in the 19x19 ladder, it’s not possible to open a third one.
There is a recurring bug where ladder games sometimes don’t register as finished. In your case:
This game: https://online-go.com/game/16355792 with Osborn12 has failed to close with respect to ladder details, preventing a third challenge by you.

Note: It may take a few days to get it sorted once a mod passes it on. I have invited AdamR to the thread as he dealt with the previous occurrence.
Aye aye, appologies about the trouble,
(and thanks for the link, Kosh ) I will let you know once it’s fixed up for you - usually within a day or two.
