Non-existant pages

As an example, see this thread
For some reason, some threads show that they have one more page than they actually do. This seems to happen when there are 15 posts on the page before them. Is this a bug, or is it caused by people deleting their posts?

It is a bug if it is caused by people deleting their posts
I don't really know what's going on
