As of this post, the problem is still there.
My profile shows me having 95 entries showing a change of points, almost all of these show a drop. I had a few submissions in the past week for points but to suddenly have so many show a drop is strange. I know perhaps one or two may have been beaten withing the last day or so but around 90 or so entries in a 24 to 48 hr period?
I can say after peeking through my profile, I've seen where at least 7 entries have lost points even though they haven't dropped in their ranking, meaning they haven't been beaten.
That has to mean something isn't right.
