I've done this mission at start of bfa but it still shows under Dazar'alor->Quests->Outposts

which parts don't get completed? on the first page of the ATT options, enable "show completed groups" and "show collected things." there should be 4 parts if you expand the scouting report.

i think these were added after the last twitch update, if you update from twitch (rather than git) you may need to wait until the next twitch update and let us know if it's still a problem then.

it looks like this for me

I update from git bash with pulling from the repo.
Last i updated was Today after i read your answer the screenshot was made after the git pull.

hmm, it's saying you're missing this quest: https://www.wowhead.com/quest=52221/mission-report-stonefist-watch

but we have the right questID attached and as far as i know those quests are not optional, so i'm not sure how you could have done the quests that come after it but not have credit for the mission report. :\

Just checking you haven’t faction changed as that can cause quests to go weird?

no i didn't faction changed.
