incorrect playlist mission loading

I started the Laso playlist with a buddy, and we jumped right into cairo station and beat it in 3 hours. we took a break before coming back to outskirts, only to find that we can only start it on “the armoury” (though, it loads us right into cairo because it’s co-op) Our playlist progress is 3/15 complete, and on the “resume” screen it says we can start it from “mission 2: cairo station” From the playlist selection screen, we can resume it from outskirts. we can select that, but after selecting the options (scoring) and getting to the “start” screen, it says we can only resume from “mission 2: the armoury” which loads up cairo station. I can provide screenshots if needed, but is there anything to be done here? this playlist seems all over the place and I honestly don’t know wtf is going on. I just don’t want to have to do cairo station on LASO again just to have it reset on us again. (i’m assuming that if we beat another mission it will put us on “mission 3” which is cairo station… wtf is that? do we have to beat it three times to progress? even a fresh LASO co-op playlist starts us on “mission 1: cairo station”. It only let’s me do the heretic and the armoury solo)

edit: also, if anyone has a working save for outskirts, would appreciate the help with a share.

I’m having the same issue, but instead of it loading the armory like it should, it is instead loading Halo from Halo 1 and this is on the Master Chief Saga playlist. Which I hope gets fixed because it was a pain to do all those levels.
