Last page of some threads not displaying?

I get this randomly. It shows another page is available (last page at the time) but if I click on the page number or the arrow it brings up the current page (next to the last page).



Here is a current page as an example. It won't display page 7, which is the last page at this point. http://ift.tt/1A2dBWb



Any idea on how I can fix this?
