Halo 4 Legendary Completion Not Recorded Help?

[FinO MommasTaco 0]

 I was finishing up Halo 4 campaign on legendary when I got disconnected from xbox live, but I did not notice this. I finished up Halo 4 and realized I was not connected, but I still got the achievement for soloing the campaign on legendary. I could not sign in due to some error (I forget the code). I restarted my xbox and signed in fine, but when I checked Halo 4 I did not unlock any of the things you get for completing it. I went to xbox support and talked with a person and they redirected me here for help. If you cannot help me yourself, can I please have a redirect to somebody who can? I worked hard doing legendary and dont want it all go to waste, because all my progress reverted back to when I was still connected. 2nd mission.

I had the same issue and i'm afraid I had to re-run the entire campaign again. 

 

Sorry, but i'm not sure if there is a way to fix it.  Maybe try Waypoint. :/

Do you know how long you were disconnected for?

I was disconnected for the majority (Since second mission), and yes I posted on waypoint too,

I redid the campaign quickly and it is marked as complete on Legendary on my service record, I have the achievements, but I HAVE NOTHING UNLOCKED. How broken can this be?

Are you sure ALL of it is completed when you were connected? Try looking at the commedations to see if it's complete.

Thanks, I got the commendations by skipping to rally point B or whatever the last one was in a mission where I didnt get the commendation, and I finished.

I completed halo 4 on legendary co-op and it shows it on my service record but when I go to comendations it doesn't show I completed it on legendary. Why?
