On Stack Overflow I'm 100% sure that I had 21,530 reputation couple of days ago (Friday, March 9th) and this morning (Sunday March 11th) I noticed it's 21,521 - my reputation history does explain the +1 for removed answer which I downvoted:
However there is nothing about the missing 10 reputation - common sense tells it's a removed question which I answered and got 1 upvote but then it should have been displayed in the reputation history.
Important to mention, the good old reputation sheet also reach 21,521 rep.
Can anyone please help me find my precious 10 points? :)
Tagging as bug since it's likely a bug in the "removed" display or calculation.
Edit: the "show removed posts" checkbox was checked when taking the screenshot - however now after unchecking it and checking it again, even the +1 is gone:
Voodoo?
Edit 2: Another weirdness:
This links to this answer of mine that was indeed upvoted on March 16th 2011 at 05:16 however both the upvote and the unupvote shows no reputation change and the weird part - that post has no activity whatsoever. Maybe someone upvoted and today his account got nuked?
