I'm missing part 3 and 4 for brin need to know 2. And 3 and 4 for yarrow shallow grave

[Mattbail11]

Same exact issue. Guess I shouldn’t have played with friends?

[yeowan]

How can i fix this?

[yeowan]

Fix found: 
You need to talk to Brin again and get an agent contract mission.
Note that it won't be highlighted on the map, you must go to Brin and talk to her.
(from the Javelin go forward, through the 2 doors, pass the fountain go up the stairs and turn right)
After this you must re-do a few contract missions from Brin, then the legendary contract will unlock. (The challenge will be unlocked way earlier...)

What if she does not have the option to talk? Do I have to wait until the endgame? 

[IchiThaKiller]

Yeah! Once end game kicks in these Brin missions will open up

[Cathoni]

so how thats is possible? i cant complete questline because of that.

[OfirKrespi]

Im missing parts 2,3 & 5. 
Iv’e tried opening another pilot, but it didn’t help..

anyone figured out a fix for this? 

I’ve already finished the game and everything, played since launch

@OfirKrespi You started a new pilot and played thru the entire sentinel faction questlines again? This would also entail doing a bit on the main storyline also.
