According to Why doesn't this question show up in the review queue for Close Votes?, questions with close votes should show up in the close vote review queue 15 minutes after "the oldest pending close vote or flag or reopen vote or qualifying edit is at least 15 minutes old".
I am looking at a question that has had 1 pending close vote for more than 15 minutes, but I do not see it in the close vote review queue. I have had no interaction with the question, so I don't think it is just me that doesn't see it.
I would prefer not to unleash the meta effect on the question, so before I link to it, is the answer to the meta question I linked to above accurate? Can anyone suggest a reason why a question that had a vote to close more than 15 minutes ago would not be in the review queue?
[Edit] The question is Why did the show's producers choose to base their Klingons on Americans?. At the moment, it still has one close vote (Unclear what you're asking), and I still don't see it on the close vote review queue.
