I didn't find a solution for this, and I can't start a new thread, so I will post my problem here. Basically, quest interactions are not coming up for me to continue the Phantom Liberty quests.
First, I am on PC, RTX 3080, Intel CPU. Post patch 2.0, I started a new character, and am now max level 60.
I first ran into this problem when I think I was doing the "Birds with the Broken WIngs" quest, where I went to So Mi, it showed interaction dialog, but then I realized I haven't spoken to Alex (optional) yet, so I left and went to do that instead. After that, I came back to So Mi, but now I could NOT interact with her at all. I loaded to a previous save and completely restarted the quest, this time speaking with Alex first before I even approached So Mi. The interaction dialog came up this time.
Now, I am currently stuck on the quest, "I've Seen That Face Before". I started this quest, and then got distracted by a bunch of other side quests, gigs, and what not, before I came back to it. Eventually, I was told to move up to a vantage point to find the netrunner twins, but the vantage point dialogue is not showing up. This time around, I completed a whole bunch of stuff, and even completed all the tarot cards, so it would be very disappointing to have to reload to a previous save with all that progress gone. However, it would seem I can not continue without doing so.
At least, I am hoping a previous save will work. I am not sure. Going to try that now. Please help, as without the dialogue coming up, I can not continue the game.
Update: I re-loaded one of the earliest saves I had, re-did the quest talking to So Mi, got the face implant, and this time, headed straight over to the vantage point. Again, the vantage point did not show up for me. So, I am stuck again, unable to continue the again, at the same place as before.
Update 2: Just wanted to let anyone who might actually be reading this that I was somehow able to get past this bug of mine. Basically, I decided to load up an old patch 1.6 save, and use that to play Phantom Liberty instead. Of course, I can not be certain that this is the action that "fixed" my bug, but the vantage point dialogue interaction was able to finally show up, after re-doing all of the phantom Liberty quests up to that point. I was also able to finish the entire DLC without any further major game breaking bugs.
