Well, I thought I had found a solution... it worked for one sim anyway: put up a card that I know is on the roster on the AH, the next sim the roster reappeared (minus the card on the AH, anyway!) So I was able to replace that player with another player and submit the team. But the next sim, guess what, the roster is empty again! But the box scores show that the replacement player "was" added to the roster successfully.
