GAME BUG: Stuck on Legendary in Progress 7/8

I played through the Campaign Legendary CO-OP, Upon completing the 7th mission the game went to go onto the eighth which is just cinematic. When this happened the screen went black and I was pushed back into the menu. My CO-OP partner was still in game and finished normally. I got all the achievements that go along with beating the camping including the one for the 8TH mission. I initially thought it was just slow stat uptake because right after this my rank showed 6/8 completed. I played some War Games and then it became 7, it never got to 8. I went back into Campaign and looked at each mission in the list all of them had the Legendary emblem under CO-OP except 8, so I got my friend again and we started that mission, it went into the cinematic, we skipped it but when it ended I got a game menu message saying to play War Games now that I had completed campaign, also the Legendary Emblem now shows up under CO-OP for mission 8. Still I’m Legendary (In Progress) This is a very annoying bug especially because it has happened to me with almost every Halo in some way or another (Unrelated to Halo 4 but still!)

Any help would be greatly appreciated.

BUMP Still reporting this issue persists, I do not want to have to replay campaign :frowning:

Not that it helps, but I have the same issue but with level 7 (completed normal on co-op and got the achievement) and had this with Reach as well

my son and I also have 7/8 missions in legendary co-op,
we also got all of the achievements for it.

my legendary solo run has 8/8

Not sure if this is the problem but i think the mission i’m missing (Forerunner) I started offline don’t know if that’s creates an issue or not but i’m not happy about having to do that level again :confused:

Mission 8 is not just cinematics.
