This morning, I had a reputation of 13,010 here on MSO. All of the sudden, my reputation dropped by 280 points to its current state of 12,730.
I suppose I lost the rep fairly and squarely (
/reputation agrees with the current value), but Recent Reputation History Changes left me with the impression that any action that results in a rep change should show up in my profile.
However, there are no rep changes registered for today (and yes, I have show removed posts is checked). Does this mean that there's a bug somewhere or are there any action that don't show up on the profile page (e.g., hard deletions)?
