I completed all campaigns on legendary everything solo except 7 missions on halo CE, which I did co op. At first I didnt get the legend achievement so after some digging I found out that the forerunner mission didnt register on halo waypoint for halo 4. So I redid that one and got the achievement. Went back to halo 5 to see if the armor showed up in customizations but it isnt there. I checked halo waypoint again but it says I dont have forerunner completed still, even though after I redid it again I got the acheivement, and halo waypoint recognizes that. I heard that you have to wait up to 10 days for the armor to show up but im worried that halo waypoint not recognizing forerunner as being completed will somehow inhibit me getting the armor. Someone help me please I put my blood sweat and tears into the campaign mostly halo 2 where I died 1600 times in 16 hours straight grinding through it. I deserve that armor for my pain lol
Update: Recieved the armor, I suppose it does just take a little while
