Huge campaign progress glitch please fix 343i

One day i loaded up reach as normal and my emblem was reset, my appearances were all reset, and my amour i had purchase appeared as bran new, even my controller settings were reset. But the main problem i had was all my campaign progress was reset i had beaten the game on legendary solo and all that was reset and i couldn’t even select any missions to do the weekly challenge on. I think this should be fixed because it in my opinion is a huge issue for Bungie to have let something like this happen :frowning:
Looking forward for 343 to bring back halo 2 as well :slight_smile:

Same thing happened to me the other day

its horrible…
