The puzzles rating I understand the need for:

I had over 4000 puzzles rating before the change too, but I like this newer system much better.
The bots thing is news to me, but it could be just a temporary bug/glitch. I hope you get it back.
The system has just reseted all the bots I've played at all levels!!! It looks like I've never played or won any of them! When I click on "play against bots" the system suggests I play with the adaptive ones as if I'd just opened my account and had no idea about chess as well!!!
I'm fed up! First the system/staff take away unfairly my 39,000 points in puzzles, and now this! Give me back my settings and my points and stop treating me like trash!! ☹️☹️
