I reported the bug via mail as well but maybe someone here has experience with it, so here we go:
Theresa is gone. The courting quest is still active but her beacon is nowhere on the map. Is there any way to spawn her/make her appear again? Maybe with a console command?
More detailed gameplay-based explanation:
Summary
I was doing the Aquarius Quest and talking to the people. Theresa appears as intended and advices me. I complete the quest. Right after that I decide to hand in the nightingale cages at the huntsman and I got the “stuck in dialogue-bug”. I had to altF4 the game. So I had to do a lot of stuff again, including the aquarius quest. So I talk to the people again and Theresa DOESN’t appear. I didn’t think much of it as I thought it might be random if she appears or not. Soon after I realized she is completely gone from the game. I can only assume that it has something to do with the just explained situation but anyhow, Theresa isn’t there anymore
.
It’s really a bummer. I really don’t want to miss out on such an important character and the connected quests even if it’s just “courting”.
