Have you found a solution? I'm on the same boat as you. I picked the right choices in the Curse of Lust, and I'm still stuck with "Speak to Roushk about a human visiting in the past" because the option doesn't show up for me whenever I talk to him/
Sadly I found absolutely nothing, I literally did everything I could, it's not that I hate the game, but it's an aspect that they should improve, show exactly what you're missing, the problem with that is that they would have to do it for each mission and it would be tedious, but I really think it would be necessary, even so, if you somehow find the error or the event to continue with that, I invite you to share the one you did so they don't have to go through what we went through lol
Good news, I found the problems, So it doesn't appear in the missions, But you need to give Ruben water, water that Roushk's wife gives you (I don't remember what the water or the wife is called lol) after that you will have to go to alden, who is in the training area in the same place, in Nortcrest, And you will have to complete his mission, which is to establish trade relations with bareshade (you just have to talk to 3 characters that in the same mission he tells you and then with Tienen, you should have no problems) and thus the option will finally be enabled)

In the part of another blacksmith, it is better explained.
