Hi there, I have played several rated games in the last few days but, win or lose, my rating has been stuck on 47.47 for at least two days or so. I don't pretend to understand the intricacies of the rating formula but it's weird not to have it change by even .01 after any games. My username there is the same as it is here.
Unfortunately, that happens from time to time and isn't related to you, it affects everybody. The played games aren't lost, there results will be incooperated once the problem has been resolved. I've notified the developer.
