The game is still saved, though, provided you close the browser. If you close or refresh the browser you get that option to continue or end the round you just quit. If you don't close the browser and go right to another game, the one you just saved and quit is gone.
Until it gets fixed, make sure the browser is closed after you save and quit. This also makes those single play tournaments unlimited now. Bet this one gets fixed in a hurry. :-)
