I recently got a new Xbox One and, after successfully installing Halo: MCC, was unable to download and install the Halo3: ODST DLC. I had previously received the ODST for free from 343 for being an early MCC player. Currently no ODST DLC appears in the “Ready to Install” section of the Halo: MCC game management menu, and the Xbox live store only provides me with the option to purchase ODST. My service record in-game and on halo waypoint clearly indicate that I previously owned and played the ODST DLC so I am at a bit of a loss as to why I can no longer access Halo: MCC’s ODST DLC.
