If you have Call of Duty: Advanced Warfare pre-loaded on your Xbox One, you should be wary of a game update that might look like it is updating the game but in reality, it actually wipes away the pre-load data and starts the download again from scratch.
This issue has been reported online on reddit as well as on NeoGAF. It seems like the users who were affected by this have their download restarted. They either seem to get stuck at 100% install with update, or start back with a 0% install.
While there is no solution to this issue so far, and it seems to be rather random, it seems to happen if you are in Xbox Update Preview Program. In that case, it is highly recommended that you stay on the latest update in order to avoid any issues.
Call of Duty: Advanced Warfare will be released officially on 4th November, 2014. Users can now play their Day Zero edition before the official retail release of the game.
