I'm having the same problem as the other inquisitor.  After starting the von wynter legacy missions, Ragna tells you about the logbook of her house. Now she keeps repeating that dialog  and the green acclamation mark remains and I'm no longer able to open the store. I was able to do some more campaign missions except now I have to talk to her again to advance the story, but guess what; I'm not able to because she keep having the same dialog. 

Please help and thanks in advance,

PSN: Kargazul 

Character name: Kargazul

Currently Ragana stuck with exclamation mark and I cant access the shop or continue the quest line

I am having a similar problem with my Artificer Omicron Arkh. He has a green exclamation point over his head and when I talk to him he repeats dialogue from an earlier mission, as soon as the dialogue is complete he still has the green mark but then hitting X to talk to him no longer works until the next time I return to the bridge after a mission, then it’s rinse and repeat!It’s preventing me from any other tech related actions such as salvaging or adding shards or codes to sockets.

my PSN is xmant2000 and the character name is Mr. X

Thank you.

I had the exact same problem, after posting a bug report and waiting for a week, I could have access to Ragna to sell/buy (what I couldn't before, because she was stuck in a end mission dialogue loop after finishing Through Fire and Flames).

I must say that I had to do the last 2 missions of Through Fire and Flames twice as I had twice the mission icons on the map, and then I was able to do some missions in Uther's Tomb, but when reached the point where I had to talk to Ragna, I was stuck as you.

Now I can sell/buy but my progress in campaign missions is stuck.
