Bug in reputation history

    This is indeed a bug with historical data that isn't apparent at all until digging into it. To be clear these are not affecting your rep, the reputation calc correctly ignores these, but the denormalized data the reputation view in the profile uses needs a bit of love...we'll give it some.

  • @Nick, I missed this report when posting mine 2 days ago: Reputation shown in graph, and mortarboard awarded, for CW posts? Hence, are you sure it's about historical data? (True, in my report it's about data for April 11th, which I noticed on April 13th. Anyway, kudos for Community for poking this question!)

    (No, not a dupe, @Daniel. See the comments at Jeff's answer below: this is about posts that were CW before the reputation was earned. Not the other way around.)

Votes like these are now fixed in the new recalcs and rep syncs happening behind the scenes, you'll no longer see invalid vote values in the reputation screen.

Actually, you're not seeing the same source of data at all, but the vote values are being fixed under the covers, I promise!


I don't see anything wrong with this?

Maybe I am misunderstanding you, but rep gained before the date a question becomes community wiki is still valid rep.

It's the votes after the cwiki date that have a value of 0.
