What should I do when I see a question marked as a duplicate of itself? I am referring to this question:

  • Now its suggested duplicate leads it to a closed question with a suggested duplicate. Talk about walking up the chain there...

  • @Makoto Fixed that, now it points to the former's dupe dupe.

Someone manually changed the duplicate notice, and linked the question to itself (probably without realizing it). I just rolled that edit back.

So I'd say, if you ever see something like that again (I never had), check the review history first (if there's no link, go to stackoverflow.com/posts/POST_ID/revisions). If it was not a bad edit, flag it for moderator attention with a custom reason, and explain the issue.
