I think your problem is that the mod code uses the variable $threadid, which is supposed to get set to the thread you're trying to view (so my guess is the one thread you're always seeing is the last news thread listed). If you edit the mod code and change $threadid to something else everywhere it appears, you should fix the problem (and while you're at it you might as well change $forumid too - I'm not sure that will actually cause a problem but it's probably easier to change it than to figure out some weird problem later).

Edit: I thought of something that's easier - change your plugin code to save the values of $threadid and $forumid at the beginning and restore them when you're done. (Sorry if you already did the editing).
