So, playing with my spouse, they’re doing beyond the barricade. My profile has already accomplished this quest, theirs hasn’t (obviously). We start the quest normally from the map point, make our way to the town, destroy the machines and advance normally to the ‘discover the clues’ step. Spouse grabs the voicemail piece and gets 1/2 completion; meanwhile, I dip into the gas house to grab the letter. Spouse’s log does not update for 2/2, even though the quest shows all three discoverable items - spouse can even read the letter and re-listen to the voicemail, but quest is still stuck at 1/2 clues discovered.
