Yeah, we had a thunderstorm at the house (I'm at work) and we've had no power for ~12hrs, but my stats say:

"Worker Name Worker Speed Round Shares (Stales) Last Share
xxxxx 0.00 0 (0)
xxxxx 0.00 251 (2) 5:11:13
xxxxx 0.00 190 (1) 5:11:32
xxxxx 0.00 124 (1) 0:16:41"

When the current round is only ~14mins old. It may be just a display issue? I have "estimated" rewards for this round, too, even though I know my rigs are down and haven't submiited a share in ~12hrs. The block stats page is correctly showing that I submitted no work during the found blocks.
