I've seen this in a few threads Front Paged at times, but rarely as bad as this. The Doctor Who Discussion Thread Currently has 4 pages showing that don't exist yet. As of this writing, pages 453-456 show up in the page navigation area, but we're only 2 posts into page 452! Most other instances of this I've seen have only been single pages. Also, the other instances have KEPT the non-existant page as pages fill. I think there's a point where the non-page reappears after transitioning to another page... Possibly due to posts it thinks exist. I have not actively even found how to set someone to Ignore (not that I've looked... I only had one instance of it crossing my mind, but that was during the Erector campaign), so I know it isn't that. I don't know if it's related, but there was a merger on the 5th, due to Search being down. I don't think I noticed the non-page-links that day. Clicking on a link to a non-existant page takes you to the top of the last real page. I noticed this on the 6th or 7th (I think 7th), but didn't say anything thinking it could be a glitch.
