So I have a dozen or so mods installed and for some reason, Visas never showed up. I think the cut scene started after my first planet visit (Nar Shaadaa) but it cut out and a different one started. Went in and out of my ship repeatedly, traveled to other worlds and tried the same thing again but she still hasn't showed up. When I got to the Ravager, Visas shows up but stands in one place and only Mandalore and the Exile are playable. When I got to Nihilus, he just glitches out and stands there. Check my screenshots. Pretty hilarious. I mean I have to start over but still hilarious. Was able to go into camera mode with Nihilus right in front of me and got a sweet shot of him.

EDIT: FOUND THE ISSUE
Open up KSE
Click on specific save game
Booleans > 003EBO_VISAS_ARRIVES:
On right hand side - Global Boolean: 003EBO_VISAS_ARRIVES > Set to YES

as soon as i left and reentered the ship, the scene happened and now I have her.
