Yesterday I set up Pinball Arcade on a new Xbox 360. I was able to download the base game with the 4 included tables and patch them to the latest version. But there's no option to download any of the table packs, either in-game, from the 360 dashboard, or from xbox.com. The 360 dashboard also thinks the game only has 12 achievements (the achievements for the base game) instead of 18. Anyone know what's going on?
