Hmm. Let me see if I can understand what you are saying.
So basically, a notification popped up that there was a new message in one of the topics that you had subscribed to. You saw that and clicked on the 'New Posts' link and it said there wasn't any new posts?
What time did this happen?
Does it happen all the time or only sometimes?
What browser are you using?
I made a change that fixed something similar to this a few hours ago. So it might already be fixed. Let me know if you are still having a problem.
