Manual Roster Editing

[oilbaron]

Anybody heard of this problem. Edit a couple of players on
the Xbox 360 version. Hit B button to exit, game asks you
to save. Save changes and override previous roster save.
Now, back at the roster screen, if I hit B button again to exit.
It should exit to menu, but it asks me to save roster changes
again. I have noticed that if you get this question, it
is not saving roster changes! Bad disc, because I just bought
an elite system five days ago.

Help

Thanks
