It’s mostly true that playlist saves can no longer be shared to other players, specifically regarding the last mission of the playlist. However, there are one or two cases in which it may work. For example, say I’m on the mission “Gravemind” in the Halo 2 LASO playlist, and I have a player who is at a different place in the playlist join in and complete the mission. That player may be able to continue on their own with the playlist and finish it out, although it may not count for playlist completion, as in OP’s case. From my understanding, playlists only register as complete when all missions have been played and the last mission is completed after all of the others have been played.
I find it interesting, however, that one can no longer join the last mission of the playlist, complete it, and get credit for it. The reasoning makes sense since the newcomer wouldn’t have put in the effort, but evidently the Solo-only missions serve as an unfortunate exception to the rule.
OP, have you tried looking at the overall playlist menu to see if it registers the completion of the playlist? I see that you have three playlists completed on that screen, but I’m curious to know if it says the same when looking at the playlist menu for all the games (by this expression, I mean where you select which game’s playlists to choose from, not the Cross-game playlists). That may help shed some light on how to fix this annoying issue. I find it fairly frustrating that the Solo missions in these playlists can prevent completion from registering if you start it in Co-op. I am now gravely concerned for my progress in the Legendary MC Saga playlist, wherein every game is on LASO difficulty, and the only way to complete the two Solo missions is to also complete The Maw on Solo, which my friend and I conveniently did not. Thus, we are now on Cairo Station, and I am not sure that those missions will register as completed, now.
The best way to combat this bug in the future, though, is to come up with a working solution that does not allow for cheating. Personally, I believe that if someone comes in at a later point in the playlist and goes to the end, they should not get the achievement until they complete the other missions. However, if someone does the missions out of order for whatever reason, but still completes them all, I think they should still get the achievement upon receiving the 15/15 on the menu, to use the Halo 2 LASO achievement as an example (343 could change the internal unlock mechanism to allow it with relative ease, although it may require significant testing). Furthermore, when it comes to the two Solo missions, I believe they should be counted if the mission preceding them and the mission following them in the playlist are both completed. For example, in the Legendary MC Saga playlist, if I completed The Maw and Cairo Station in the playlist, I should receive credit for completing Heretic and The Armory, regardless of whether I actually played them, which makes sense since one is a cutscene and the other is just a slightly more interactive cutscene, both of which hold no difficulty on LASO. Thus, I believe a good solution is the following:
- When a player completes every mission included a playlist through the playlist UI, count the playlist as having been completed, both in the UI and for the achievements, even if the missions in the playlist were not played in the predetermined order. The player has still proven their abilities and shown that they can complete the playlist in order, as the missions are independent with the exception of story progression. Also, it is worth noting that this rule does not mean that the playlists should have missions on-demand. Instead, it is meant as a fix for when missions don’t count during normal progression, or when joining in on the journey on a later mission. - Give credit for completing the Solo missions in Halo 2 (Heretic and The Armory) when the missions preceding and following them are completed in the playlist. In the Halo 2 playlists, give credit when Cairo Station is completed, as no prior mission exists. This way, even if the playlist is played entirely in Co-op, completion is not withheld from the players.Hopefully, you won’t have to recomplete the entire LASO Campaign, as it can be very rough at times. I’ve completed it twice, and my conclusion is that Regret is easily the worst mission in the franchise for Co-op LASO, although Gravemind can also be rough. Good luck, OP!
. The achievement not unlocking was due to how the game checks for completion, which is a terrible design. I have since got the achievement by picking up the regret save I mentioned in my last comment and replaying the last 7 levels for a 2nd (in some cases 3rd) time. I have also helped 2 others in the same position get the achievement.
