I can still see all of today's expired sweeps. I wonder if the problem is in SA because I can see the sweeps when I am logged into Sweeps Plus? I used Contact Us to report the problem to the Admin. I'm guessing that many other people also reported this and the Admin is busy working on it.
suggestion: on the front page of SA, go to the category you want ie: daily, one entry or whatever. click on it and sort according the expiration date ascending. This should get you by for today.
