I'm still having this problem and I don't think it's a problem with the cache (I've cleared my cache and refreshed the page too).

I'm still seeing this: The "last post" that shows on the main forum page in the small right had frame (the column right before the views/replies) is somehow missing when I click to view the threads on the forum. I can view it if I click the live link from the main page, but it is totally missing from the forum page listing of threads.
