Yesterday, stats.SE showed I had a rep of 503. Today, it shows I have a rep of 501. The missing 2 points are not listed in my activity anywhere.
Furthermore, meta.stats.SE still indicates that I have a rep of 503.
What's going on?
Reputation changed unexpectedly? Don't know where to turn? We've moved heaven and earth to ensure your score is always correct!
Per the system message currently showing at the top of the page, we have performed a global recalc of everyone's reputation. As a result of the new changes, your rep will be in sync.
Check out your reputation history for October 1, 2011. You had a post that was deleted and the rep change came from that. This is now visible in your reputation report and going forward will be less confusing.
