Well its not an error, its in the list of replies up the top before you actually read the reply's. I get a subscribed thread in my user cp and i click the arrow that says go to first new post, but there are no new posts. The 8th or 9th reply in the list has an orange square indicating a new post but the title for it is More replies below current depth and when i click on it it doesn't do anything apart form go to the last post which I've seen. It's happened a few times?
