One last drink bug

[Verltei]

Spoke to Ruana first and couldn't get her to come, came back to her after the other two and captains quarters, and now can't swap drinks as I discussed to get her to come in the first place.

This happened to me too. I think it might be glitched. >_<

Edit: I've submitted a ticket to Obsodian, linking this post. Hopefully it will get resolved in a future patch.

Also, I'm wondering if this is the case for you to, Veritei, but I think this might be because of found the book on poisons before I started the quest. I had the option to let Ruana know about it the first time I visited her, but I didn't even remember the book/ link it to what's happening, so didn't mention it. When I came back, I still had the option to convince her to switch out the mugs, which she agreed to and heads to the meetup with the understanding. Only for the game to decide "nah... death to her".
