Achievements Not Unlocking? (Solved Itself)

Hey I just completed my Solo Legendary playthrough to unlock the “Forging a Legend” and “Lone Wolf” achievements, I put a lot of blood, sweat and tears in this and I finally finished it today… only for the achievements not to pop afterwards. I don’t know what went wrong but my service record states that I’ve completed it Solo on Legendary and I even got the Legendary Ending afterwards. Does anyone have any idea how to fix this?

Edit: Nevermind they ended up poping a little later then I’d like.

This happened to me, I came on the forums to vent.
Next day those achievements were unlocked but I got no notification.
I guess they are just a bit buggy. Considering the developers, I’m great fun they at least unlock.

My just appeared out of nowhere… thankful I wasn’t playing to do that again anytime soon.

The exact same thing happened to me with the same achievements. I found out it was because i started mission 14 online but finished it offline causing it to glitch and not count (this sucked the most because the 3 wardens on legendary are insane), also mission 8 which i did 100% offline didn’t save either. Pretty much just make sure you do all the missions online with wifi the whole time.

I had this on the mcc as well, all the halo 2 achievements from easy to legendary didn’t unlock for a good month then out of the blue i got 16 achievements for all of halo 2 and for doing every campaign on legendary. So i’m guessing it’s a bug on the Microsoft side.
