Today Wizards of the Coast released their second expansion for the XBLA game Magic the Gathering: Duels of the Planeswalkers. While the expansion features a slew of new features such as new unlockable cards and new playable decks, the accompanying patch which adds the content to the game renders Duels completely unplayable to anybody who downloads it.
It looks like they have officially fixed this issue. Players will be prompted to re-download a new version of the game upon launching it. In addition to the changes listed above, many interface and audio changes have also been made.
