Can no longer navigate through multiple pages within a thread on Breaking Bad message boards

A message board thread I am viewing has 189 replies. On the topic listing page, below the title of the thread in question the pages are listed as "Page 1, 2, 3 ...last." Usually when I click on a thread and there are multiple pages, there is are "next" and "previous" links that allow you to navigate through all of the replies. For this thread, though, none of that appears. I can only navigate through the pages by returning to the topic index page, and clicking on the "1," "2," "3" and "...last," so I only get the first three pages and the very last page. I can find no way to access the pages in between.

I had some luck by using the mobile site on my phone, but while I was able to see more content than I could see on the full site for this particular thread, I could only access ~ sixty of the 189 replies (i.e., the "next 20" button only appeared two times as I scrolled through the replies).

Here is the thread in question: http://www.imdb.com/title/tt0903747/b...

P.S. I checked the boards of a couple other shows, and those had the page navigation buttons at the top and bottom of the thread, so the problem is not with the entire site. Maybe it's just the Breaking Bad board?
