New posts not displaying in thread

[Epictetus]

I noticed in the Rome Total War 2 thread some new posts were not displaying. If you go to the last page, page 11, the last post is from four days ago and doesn't show three new ones. The URL of that page ends with:

...?start=150

I found that if you manually change it to:

...?start=155

you can see the last few posts.

For some reason it is not displaying a new page, page 12, or something.
