When will the rating rollback bug be fixed?

When will the rating rollback bug that caused performance to decrease in recent contests be fixed?

My rank has improved, but my performance has decreased.

I also wonder, for people with <= 6 contests, they increase the rating a lot, but these are points lost by others, which is really unfair.

    I think cheaters should have their ratings cleared in order to repay the loss of legit user ratings.

    I think it is more like they have a set rating of 1400 which is not showed to them in order to preserve moral, most people who start cp are not 1400+ rated so they would see a rating drop off get demoralized and leave. so they are not getting rating lost by other people rather they are getting 500+d1 and 350+d2 where d1 and d2 are the actual increase from 1400 so if someone get's +350 after the first contest it is actually — 150 from 1400 and the rating algorithm now views their rating as 1250 while they see the rating as 350 and so on it takes 6 contests to normalize the rating where rating after the 6th contest is usually their true rating.
