Sometimes for Ocean's Eleven, a game will be rated twice in succession. It has happened to me twice now. In my most recent experience, I lost 22 points and then 19 points. I received two different messages, and for one game lost a total of 41 points. The game itself was very close, coming down to the very last card and he won 6 to 5. But regardless,, losing a total of 41 points for one game is not right! I have written the webmaster a few times about this, but he does not fix it. Has anyone else had a similar experience?

Yes, not recently but this has happened to me twice. Once I lost double points, the other I won double the points. So not a major disaster but it would nice this to be fixed.

Just happened again, I lost Oceans Eleven game #2363382 and got two messages and game was double rated (even with the newly revamped rating system)

I wonder if it's a bug just with Ocean's Eleven or with the broader, newer framework it uses.

Has anyone noticed problems like this with Tumbleweed or any of the Chess variants?

It could still happen in the new chess variants. But this bug has now been fixed and ratings are recalculated according to more or less the original rules.
