According to the reputation league for last week Andy E earned 3,443. Curious to see how he did, I checked his reputation graph, but he only he earned ~1700. I understand that the reputation leagues are a snapshot, but a difference of more than 2X seems a lot. Was this due to voting irregularities that got rolled back, or is this a genuine bug?
This is fixed now.
Whenever a moderator recalculates a user's reputation, a rep-league recalc is automatically triggered as well. But we had missed the case when users recalculate their own reputation.
In this case, Andy E recalculated his own reputation, resulting in a big rep boost, which was then mistaken as genuinely earned reputation by the leagues.
