I just saw my points for this jackpot drop from about 92,000 yesterday to about 83,000 today. What might have caused this?
Sometimes research projects make adjustments to work units that can affect your points here at Charity Engine. They do this to ensure that points are distributed accurately, and sometimes it may result in points being removed.
In your case, it looks like about 13,000 points were removed, but then 25,000 points were granted the next day, so it was likely a temporary snag. Sorry for the inconvenience and thanks for bringing up the issue -- and for participating in Charity Engine!
