So this is slightly random, from what I've seen in the comments... I bought the digital download on my 360 this morning, and had no issues playing it. My brother tried to get on with his account on the same console, and the content is locked, saying he has to buy it. I've never had this issue before, where only one player can use a game/dlc from the same console, so I can only think it's part of the bug, and wanted to make sure it was reported.
