After playing the halo 4 campaign on legendary solo for about 6 hours and getting to shutdown, I was happy I was nearly finished and have the achievements and the Mark 6 armour. Though I came on halo today my campaign was reset back to the prologue, though when I look at my commendations, I have finished up to shutdown, it also reset my armour, load outs, season pass content and my rank by 3 ranks. Is there a source or resolution for this problem because I really can't be bothered to redo something I spent hours doing due to shoddy development. If anybody else has this problem please post.

We should get something for our trouble, we should get something for their shoddy work, I have had the same problems with every Halo since Halo 2, I know about the company change but there has to be a way around this problem and because of EVERYTHING on my account reset I don't know I could be bothered to do it all again.
