BTW despite the lack of response from EA I figured out the dissapearing players issue.
What happens is that if you have injuries the game takes that injured player's cap space off your total show and shows you have more cap room.
IF you add players into that cap space instead of adding them to the roster it "dissapears them" from the game.
So what as happening to me in the last season was that IF the 4 guys I had injured came back I would have been near the cap. Since the players I brought in to fill those holes added addition cap the game didn't see I had the extra cap and just made the players vanish, or random plays vanish to make up the difference.
