So I have done everything except Silena's quest and have spoken to Redbeard and gotten the final meeting quest. And still Silena won't advance the quest. I quit and went back to an earlier save & redid the Redbeard conversation where I get the final meeting quest again. She is same as ever. I have been to the site with her several times & have said I would help her. Why is this stuck? I don't want to go into the endgame without this, but it won't trigger, & I have researched & know it is supposed to trigger now (and it is my last chance). On a Mac, running Mohave 10.14.5, have not installed any cheats or messed with the program in any way.
