The question titled, How many names can a dolphin remember? has gotten a close vote which is more than enough to send it to the close vote review queue, however I don't see it in there. I have confirmed this in both regular and incognito browsing mode.
This was the same problem that happened on the last two private beta sites, so therefore I suggest an investigation.
The Close votes queue includes questions that other users have flagged as needing to be closed.
