I made a topic about this about a month ago, and the topic is now labelled as "Fix Deployed." Essentially the issue is that the list of topics page is creating the next page number one post early, before there is actually a post on it. Now, this did get partially fixed, as sometimes it will work (I personally tested a topic with 10 posts and it didn't add the second page link). However, I'm still having issues with this occurring on some topics, the most recent incident I noticed occurred with a topic reaching 5 pages. So the fix clearly didn't fix it all. I don't know how much more information I can give, other than the fact that most topics are still sometimes listing the extra page number on the topic listing that leads to a blank topic page a post early (whether it's related to the number of pages, I'm not sure).

Edit: Actually, it appears to not be so much a bug, as the fact that the page numbering updates faster than new posts, which is why with an active board, I might be seeing additional pages before the posts are actually updated and added.

Edit edit: De-strikethroughed initial post, see second post.

 I will have Aaron look at it again.  He was pretty sure he fixed it.

Thank you for all the extra work!  Aaron will get to this soon
