I've been experiencing the same glitch. Here's what happens - if you were reading something in the category of "Lost Pets" for instance, when you hit the "go back to forum" button, only topics for that category will be shown. And more than likely, a lot of the threads will be old ones. I have to scroll over to the left to "Forum Categories", make sure all are checked and then click "Update". Then everything will show up correctly.
