So a lot of my friends and I have been playing fallout four since the release. One of my favorite parts about the series is to jump in with the brotherhood of steel. Well I choose to join them after the raid on the jet facility, the next mission I did was cleansing the common wealth then I went and did the quest "the lost patrol" and got the old paladin (name?) to rejoin. Then I completed 3 of each repeatable quest with both the knight and the scribe, which both had to do with getting old teck and or clearing out an area. Paladin dense still doesn't have a new quest for me, where as my friends did one quest for each the scribe and the knight and then got a new quest. I would really like to continue this quest line but it seems as though its all glitched out and only lets me do these repeatable quests for the brotherhood. The only helpful thing danse had said in his chat when I try to go up to him was something about it being easier when the scribe Haynes gets the antenna up.

Also the quest semper invitica disappeared and it completed.

you have to keep playing the main quest line and then it picks back up you can't miss when it picks back up when you complete a main quest literally a giant ship flies in the air. hope that helps

Similar problem here, Semper Invicta finished, extermination and tech recovery quests done a couple of times, no further quest from the Brotherhood.
During one quest where you have an optional objective "Talk to the Brotherhood" to get help, Danse does NOT open a dialogue interface so I cant progress the quest Molecular Level.
Furthermore the airship Prydwen doesnt appear ingame.

Possible Spoiler below for main quest....




The airship shows up after you find Kellog in the main quest.

It didnt for me, nothing in the sky even tho 2 npcs actually mentioned looking right at it when I was next to them. 30+ hour save game down the drain, hoping starting from scratch will let me finish the BoS side of the story,
