I am wondering if there's a bug or I missed something obvious.
I recently - a few days back - got the (bronze)
self-study tag badge (I've had a few others before).
I then noticed in my tag-list that I had more points in the histogram tag, but I have no badge for it. Currently no users have that badge* (two of my answers under this tag have over 70 points between them which is why it's so high for me).
Here's my answers in order of votes if anyone wants to see them.
By my understanding, bronze tag badges are awarded when:
The user has 100 points (upvotes minus downvotes) on answers under this tag (check)
On at least 20 questions (check)
Only non-community-wiki, non-deleted answers are considered
I think I passed the second of the first two requirements maybe a week ago (probably the points boundary was passed second, I wasn't really watching, I know it was close a few weeks back).
"Community-wiki" I hear you thinking. I know I did. But I checked my answers on the tag - I can't find any CW questions or answers among the ones I have answers on, but in any case, even if I missed some, I have been through one by one and I counted over 100 points and over 20 answers without CW or deletion.
(At least one of my answers became CW at one point - I've edited and updated enough times to trigger CW - but that CW was removed on request long ago. I wouldn't think that this would affect the badge though.)
* I note when checking that first link in my question that this page and other badge-related pages have recently changed... but I doubt that could affect anything either.
Edit: I note that only 18 of my answers there have positive points... but again, I don't think it could be that.
I'm not all that worried about the badge, but I'm at a loss to explain what the cause of it is (and if it happens to me for whatever reason, presumably it will occur again, so in that broad sense it's certainly a concern).
I've tried searching meta on SO as well as here but I can't figure out what the issue is.
Did I miss something? Or is there perhaps a bug of some kind?
