Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

This is something I noticed:

As per my rep records, I just lost 15 rep as an unaccept:

When I went over to the answer, the timestamp on the now-accepted answer made no sense:

How is that an answer which was accepted 2 years ago, made me lose rep now?

Looking at the timeline, I think this is what has happened:

enter image description here

  • Ganesh's answer was initially accepted.
  • In December, my answer was marked as accepted.
  • Today, my answer was marked as unaccepted.

So, does this mean that unaccepting my answer resulted in the previous marked as accepted answer being marked as the-current-accepted-answer, even though the timeline doesn't explicitly say it has been accepted?

Or is that the timestamp on the once-accepted-answer isn't updated?

I did NOT even know that /timeline/ existed. Thanks for that :) – Manishearth Apr 7 '12 at 10:24

This happens when a question is merged. For accepted answers THERE CAN BE ONLY ONE, so the earliest wins. You can see that a merge happened here:

Kudos to balpha for finding that, I thought we had a phantom double accept cleanup job I was incapable of finding and was going slightly mad.

Aha, so my answer was accepted on the previous question, the merge meant the question had 2 accepts, so my answer was unaccepted? – Sathya Apr 7 '12 at 12:52
@Sathya - yup, exactly – Nick Craver Apr 7 '12 at 12:53
Makes sense, thanks for clearing that up! – Sathya Apr 7 '12 at 13:00
