Hello. Not sure if its on your end or what, but since I finished the main campaign today I went on to play harbingers of hate and for some reason none of the missions will appear on the star map anymore in any system.
Also the random quest astropath on the bridge keeps telling me I have an active quest but none show. The tarot missions still worked, but after finishing a quest the lootscreen/post quest rewards and so on did not appear at all unless I went to the empty starmap. In one instance the results from two prior quests appeared there. This applies to all the characters, I even tried making a new one and when I got to the third mission part it just had a black screen and I had to close application. 

I had a friend do online shareplay on local co-op that day so no idea if that affected it, or that I installed some of the season pass dlc today. 

The quest I was on is still displayed on the top right of the screen and says: 

"assist in the defence of the tempestus citadel 

clues:0/9" but cannot be selected or visible on the map or even moved to with right trigger shortcut, the same as all the starmap quests.

I'd be very thankful if you could look into this for me please as I haven't been able to play the game at all anymore.
