So yesterday the second TU came out and my multiplayer stuff got reset back to default and I had to watch the video over again. I checked to see if all my stuff was still there and it was so I changed everything back and got put back up to SR-29. Later I tried playing the final mission on Heroic with a friend so I could get Bromageddon and that was the last mission to do for me to get it. I tried it with one guy he lagged like crazy and eventually lagged out. We tried again with a new guy this time. Connection was even worse and I lagged out and got off. Later I got back on and played matchmaking, got off and played again earlier today. I played online then got a friend to try the final mission with me. I went to the campaign lobby and it was on Prologue-Start. So I tried to change it back to Midnight-Rally Point Alpha and Prologue was the only mission I had. So I played it then skipped it then did a little bit of Dawn and saved and quit. I checked my memory on the Hard Drive and it said the data was still there. I checked my service record and it showed when I first completed campaign. 11/16/12 Solo on Legendary. So I did the mission with my friend anyways on Heroic. We finished it and I didn’t get the achievement. So I just did Spartan Ops and more War Games then got off. I just came on here to look at my stats and all my acheivements have been locked and all the terminals have been locked too. But it still says I beat the campaign on Legendary Solo and Heroic Co-Op. Here’s a link to copy and paste.
