ServerFault doesn't generate very many re-open reviews, today when I looked it showed there was one question to be reviewed. Even though the counter only showed one, after I dealt with that, I was shown this question:
I clicked through to get a better sense of what the question was, and found it wasn't closed, didn't even have any close votes. The question seemed fine to me, so I selected "Re-open", got the usual dialog box "Nominate this question for re-opening?" and when I was done it showed I'd done two reviews today.
I thought review tests had some sort of dialog afterward to tell you what just happened, but there was no message about this being a test, it behaved just like a regular review.
So was this a glitch?
