okay so i go to play halo 4 and i need a 30mb update (download) then after i re create my classes (they reset) i check my specializations and im missing 1. Im rank 114 (love halo) and the last one i need to do is gone (stalker) and i dont know how to get it back i would really like some help coz if i cant get to top rank ill cry 
and if its gone forever i think i need some kind of armor (locus,deadeye) 
but if anyone else has this problem and has fixed it please help me. Thank you
try look into your download history and re-download the specialization classes
Head to the following URL:
https://live.xbox.com/en-GB/Download/History
Re-download the Specializations (Infinity Actual Kit for Limited Edition owners), then restart your console.
will that get rid of any of my rank or specializations or anything?
> will that get rid of any of my rank or specializations or anything?
Nope, it will just (hopefully) show the last Specialization in-game!
I have this problem. Just keep restarting your Xbox. I have redone it over and over agin it still does it. It’s a problem with the server is what Microsoft said.i lose all my preorder stuff all the time its annoying as hell. And there is no real way to fix it by the player
i dont even know what im ment to be deleting here lol i pre ordered and had the specializations but then i entered the code for them coz i thought that would fix it but it didnt and i cant find them to delete
I had the same thing happen. Redownloading it didn’t work so I no longer seem to have access to them.
