The question https://math.stackexchange.com/questions/132072/does-doing-mathematics-make-you-more-intelligent was closed, but 13 minutes after closing there was an answer posted.

I suppose this is a bug, and not a feature of the software.

I think it might be intended behavior. I remembered that there was a similar occurrence on MO; this meta.SO post is where Andrew Stacey filed the resulting bug report. Apparently the resolution was that

We now block answering after a reasonably large amount of time has gone by.

I can imagine that 13 minutes would qualify. However, I would have thought that, now that SE pages are almost-real-time updating with comments, answers, votes, etc. that the above answer would be out of date and that closure would take effect immediately, without someone having to reload the page.

  • $\begingroup$ Yes, I was aware to the MO threads, but I figured that the software on MO is very outdated and the problem was corrected on SE 2.x versions. $\endgroup$
