I cannot find Pavarti on my ship. Every time I enter the Unreliable, I get an announcement from ADA requesting that I have Pavarti send SAM to the bridge. When I get to engineering, I only see SAM, staring into the space where Pavarti should be. I've searched all over the ship and I can't find her so I'm assuming this is a bug. I noticed this after completing the Monarch questline, but not soon enough after that I can guarantee a link.
EDIT: THIS ISSUE HAS BEEN SOLVED
If you can't find a crew member aboard the Unreliable, just take them on your shore party. In my case, Pavarti fell from...somewhere and hurt herself, but returned.
