Demoted for winning was fixed right??

No. You can still get demoted for winning and this is not a bug. The thing is, you're not really getting demoted "for winning". You're getting demoted due to your overall performance over your recent games. It just happens that you got demoted after a win but really you were in line to get demoted regardless. I know that it is weird though. Why didn't they just demote you after your last loss then? My guess is that you need to have played a certain number of games below or above a certain hidden rating threshold to get demoted or promoted. Probably your rating dipped below the threshold a few games back. Your win wasn't enough to bump you above the threshold and that win marked the number of games necessary where your hidden rating was still below the threshold so you got demoted. Just a guess, but it would explain how you can get demoted after a win or promoted after a loss.
