HELP: LEGENDARY PLAYLIST PROGRESS ERROR

Games Halo: The Master Chief Collection
1

So I just completed Halo 3: ODST’s legendary campaign playlist however I wasn’t awarded the achievement for completing the game. Upon checking why, the progress counter on the playlist says I’ve completed only 16/17 missions in the playlist, somehow it didn’t track that I viewed/completed the epilogue, even though I did. Now, when I go to resume the playlist, it says that I can only resume from the second mission? So I have to play thru the entire game again, on Legendary, just to view the epilogue. Am I correct in believing there is no way to select which level to continue from in a playlist? I have included a short clip recorded on my Xbox illustrating the Playlist showing that my progress is 16/17. I have browsed the forums and seen a few others have raised this issue, are 343 aware of this and is a fix being developed? Having played the game thru purposely on the hardest difficulty for the sole reason of obtaining the achievement to not be rewarded it is pretty annoying, also, were I to play it thru again, how do I know that the progress would even count? Is there anyone extremely close to the end of the game who I could join to view the epilogue with or does anyone know a solution/fix for this? Any help would be much appreciated.

Just to note, I completed the playlist with a friend and all progress counted for him.

For the Legendary achievements, you don’t need to play the missions in a Playlist. They don’t even need to be in order. Looking at your Service Record, it looks like ONI Alpha Site did not register. I suggest playing through that one again.

You do need to use a Playlist to get the LASO achievement. And unfortunately you probably did not receive the 33% credit towards “play 3 ODST playlists” that you should have. Since there are quicker playlists out there, I would just use them for your 3 playlists.

As can be seen from this thread, the Campaign playlists are rather buggy. I suggest just using them for the achievements that mention “playlist.” Then use the usual Campaign mission select for everything else.
