Ashara Missing

 Hi, I'm a Level 43 Sith Sorcerer and I've been playing for a long time. I just came back to the game and just realized I don't have the companion Asmara Zavros, and I am fairly certain that you get her before Tells Drelik and Revel, as she appears in my ship during cut scenes. I haven't been able to find anything online but this is somewhat concerning. I don't know why it happened, as it was a long time ago but if there is a way to solve it that would be really great. If now, I mean I've played the game without her.
