Hello,
this seems to be a recent bug, since I remember previously viewing Chess rankings with bots and it worked fine before.
If you open statistics, and make sure to choose a game which supports bots, in my example I selected Chess. Further down, I selected to view statistics for games with bots only, and for all languages.
It opened https://qcsalon.net/en/stats?game=13&glang=all&bot=1
however, the page just says No game counted so far

It seems like you can't view statistics with bots for any game now. Trying the same thing with 1000 miles I noticed exactly the same results. The statistics work fine only if you choose to view all games, or only games without bots.

Thanks.
Edit: It also seems like if you choose the option without bots, this shows exactly the same statistics as if you chose any bots. There is no ranking displayed like usually when you choose without bots.
