All missions CO-OP Heroic achievement bugged!!!

I beat all missions on coop heroic and achievement does not unlock. I look under campaign stats and all mission are complete in coop. Is there going to be a fix???

I have noticed this happened to a lot of my friends for the coop completion achievements. Go to your service record on Waypoint and look at what missions you need to do again.

when i went through the campaign the first time i lost internet half way and finished the game. didn’t get any achievements cause for some reason even though i got connection back halo still wasn’t connecting properly. i’d say try hard rebooting your console and see if you get them

Did that and did not work. I was host for every mission and we never disconnected. :\

It says they are all done. That was the first thing I checked so I could go back and re-do but sadly it says all are completed.

It doesn’t say which mission im missing it says they are all complete on heroic co-op

Same problem here. Hopefully 343i releases a fix.
