I think I might see the problem. Try swapping the rank restrictions around. 13k on the left and 6k on the right.

we should really change that to a slider or something so this error is impossible lol

Or do what the “Create Custom Game” option does at https://online-go.com/play - when changing the one, automatically change the other to ensure it’s never an invalid range: there I figured out quickly enough which should be which, thanks to that feature.

this had been discussed but I never realised it was implemented! 
yeah, that should be good enough… I still think a slider makes the decision more intuitive though and minimises confusion for new users…

It could be an option in settings that you can disable. I think it should be auto on though. Some people on these forums have trouble finding something in the settings, and this feels like something that could be helpful for them.
Thanks for thinking of that! That’s probably a good enough reason to just leave it how we have it
