so I beat the legendary campaign(or so I thought I did) and I accidentally skipped a mission. (I saw this on halo waypoint when I didn’t get the achievement). It now says I am 86% of the way through with the lone wolf achievement, but halo waypoint says ive done them all solo, but I still don’t have the achievement. I posted a help topic in forrums so they told me to come here.
