[Locked] Life Story Achievement bug!

OP inFINN1te

So I beat the Master Chief Saga playlist and it said for some reason I didn't do The Maw and Heretic and had 44/46 in the playlist done. Which makes no sense as you can't get through the whole thing without doing those but whatever. So I go all the way back through CE and the beginning of 2 in the playlist and am now at 46/46. This happened 3 hours ago and still no achievement pop up. what's going on?
Did you do it co-op?

Yes I did.
Unfortunately, The Heretic and The Armory from Halo 2 are not playable on co-op and are automatically skipped on any playlist that has them without warning. In the 2 crossgame playlists that contain them it seems to give credit for the Armory but not The Maw or The Heretic. Even more unfortunate is the way that playlists seem to check for completion. Even if you play back through Halo CE, complete The Maw and The Heretic solo, it will not trigger the "check". The check seems to only happen when you beat the last level of the playlist. I recently made a post about this when I didnt recieve the back for more achievement after completing Halo 2 LASO: https://www.halowaypoint.com/en-us/forums/84ad72a8b51847978545f685f651fc15/topics/psa-playlists-on-co-op-laso/b43747ff-e644-47fd-b4c5-6d8685111d95/posts?page=1#post2

So would Xbox support not do anything to give me the achievement if I contacted them despite earning the right?

I seriously doubt it, but you can try. To me, it's not a glitch so much as it is a design flaw. The playlist achievements do unlock... You just have to do it the way they designed it, even if it is a really bad design. I didn't try contacting xbox, rather, I messaged someone from 343 directly. He said "they were looking into it on their end", which they very well may be. But that answer was just generic enough that I decided to try and resolve it myself in the meantime.
Hey guys, what ended up happening for you?
Did you replay the whole playlist?
Did you play up until that the end of the cinematic missions on solo and then find someone with the checkpoint for the last mission again?

This also has just happened for me where it says the maw and heretic are incomplete .. completed the whole playlist and had 44/46 also.

Played the playlist again and completed CE and the made it into H2.. it didn't count and I would also note that I played out the whole cutscene after the maw just to be sure and the game black-screened after that. I still was able to use the Xbox so it hadn't completed crashed, so had to re-launch the game with still no success.. I believe
Kancer On XBL said the checks happen once finishing the last mission of a playlist so I suppose I have 3 more campaigns ahead of me again...

By replaying the entire Master Cheif Saga playlist, did the achievement pop up? I have the same problem...played Co-op, now I am at the last level of H4 and noticed I was missing 4 missions instead of 2 (Midnight and the Epilogue of H4). The missing missions are The Maw and Heretic :(
Just finished the playlist in co-op. 44/46 missions, The Maw and Heretic are marked as not completed.

I really don't want to play the whole thing again just for a stupid bug. Please fix 343.
Yes it happened to me too. Please could someone fix it? We put in hours on coop. This is a long time noticed so maybe someone should make it only solo. Thank you!
How is this not fixed yet? I just did this co-op with my friend and NOPE! Please give this some attention. Please. Thank you. ❤️
A lot of time and effort goes into trying to get these achievements. It is pretty disheartening when a bug like this occurs. Hope that it is fixed soon.

thank you,

avid halo fan
Awesome same issue here. I dont understand....
Anybody else crying themselves to sleep tonight over this?....
I just played this entire playlist over the course of a week with my friend b/c I thought that for sure by now 343 has fixed this glitch. I had the same issue back in 2018 and had to basically replay the whole playlist solo again in order to get the achievement to unlock. I feel really bad that now my friend has to do the same thing too because I didn’t Halo Waypoint first. This game has been out for over 5 years now, so I doubt if they haven’t fixed this glitch by now then they won’t ever do it. What’s interesting though is that they keep making updates to change the backgrounds of the game, menu layouts, and other things but then they don’t actually fix the issues that people are complaining about on here. I’m definitely crying myself to sleep tonight. At least we didn’t play the Legendary Master Chief Saga playlist.

It's possible you can get your friend to get around this issue.

If you can find someone with a checkpoint near the end of the whole playlist, just have your friend finish Halo CE through the Armory in Halo 2, then get your friend to grab the further checkpoint from another person.
As this appears to be an issue with your game, we recommend heading over to https://aka.ms/HaloSupport for further assistance. Please review the latest known issues and submit a ticket if your issue is not listed.
