Legendary Achievements Not Working

I have beaten Halo: 1, Halo: 2, Halo: 3, and Halo: 4 on Legendary difficulty by myself (I also beat ODST on Legendary but I believe that's irrelevant) but I did not receive the achievements Veteran, War Hero, Legend, The Legend of 117, or Lone Wolf Legend.
Basically, I got the achievements from 1, 2, and 3 but 4 didn't register for some reason which prevented the rest of the achievements from working. I also didn't receive the Helioskrill armor set in Halo: 5 which is supposed to be gained when beating all games
on Legendary in Master Chief Collection. I double checked to make sure that it says I've beaten all the levels of Halo: 4 on Legendary and I have so I'm positive it's a problem because I've seen multiple forums where people had similar issues. Thank you for
reading and please resolve this issue. My gamertag is and my email is
[mod removed] in case it was needed.

Isnt the achievement to play legendary solo? Or you just playing for shits and giggles?

There's one for doing it legendary solo and another just for legendary. Playing it solo will net you both achievements.

legendary isn't easy. One shot and your dead. Need helper's.

[/quote]Not true. Unless they're using power weapons/shotgun etc.

 

Heya PoccoGodOfSkool.

Sorry to hear the achievement hasn't unlocked for you! For achievement issues like this, please give the

Achievement Troubleshooter a try. If the steps there aren't clearing it up for you, make sure to follow the link near the end of the troubleshooter to fill out the survey. Once you fill out the Achievement survey, the right team will be made aware of your
issue.

 

I performed the steps shown in the Achievement Troubleshooter but they didn't work. I'm already connected to Xbox live, it's been several days since I earned the achievement, I've hard restarted my Xbox multiple times, and the achievement is still not unlocked.
If I look at every single mission, it says I've beaten them all solo legendary. Is there anything else I can do?

 

Hey there PoccoGodOfSkool!

If the steps in the troubleshooter didn't work, be sure to visit the survey in
this forum post as outline in it. So long as you fill out the survey the right team will be made aware of your trouble.
