Fable II taken off Xbox Live

Gamespot report that Fable II is no longer available for download over Xbox Live, and people who have purchased the game digitally are no longer able to re-download it if need be. However, the two DLC packs - Knothole Island and See the Future - are still available and as Microsoft have yet to comment on the issue it is unknown whether there is some issue at hand or whether it's simply a mistake of some kind.
