After the recent educational round 102 which should have been unrated for me as I was a master (2161) during the round, I was shocked to find out that my rating had dropped 221 points! I think there is a bug in the rating changes. Is this a common mishap that has happened before or is there anyone else who has suffered the same? Please let me know on how to get this problem fixed and hopefully this does not happen to anyone else in the future!
