I've had this issue before the update came out, nothing changed, sadly.
The quests for the main story are just gone in my game. I am playing on PS4 and had no major issues at all up to this. I have literally completed all other areas, the Winchestre Arc is the only thing left to do in order to progress/complete the story. Well, after I killed the first of Aelfred's targets (the Gallows), the quest marker just completely vanished. From the map, from the questlog. The two Ravensthorpe quests are still showing (Breaking the Order and A Brief History of the Hidden Ones). The Order menu tells me I need to further progress the story to find the other order members (obviously the two others in Winchestre.) I know other people had problems with the "Plucking the Quill" quest where they weren't able to interact with the girl. I reckon this is the next quest for me, but others still had the quest marker showing. The last thing I remember I had to do was meet Goodwin in the Nun's Minster; I found out a cutscene was supposed to play as Eivor enters, that didn't happen in my game. Goodwin is just standing there. Quest and questmarker have vanished. I don't know what to do, I literally cannot finish the game.

Would really appreciate a fix or some adressing this issue at least!
