During a mission I guess Prav died? Her health meter never went below 50%, and after the mission I fast traveled back to town her character was just on the ground, laying there. Her health meter was now full. I could not click on her to talk, I can access her menu for items, perks and what not. I can't see her in the ship either when I'm there. I changed her out for another companion, no problems with that companion. When I put Prav back in the group, same thing, her body just followed along on the ground, popping up as we traveled. When I talked to NPCs her dialogue would come on, but you can't see her and if the NPC talks to her, they are kinda looking at the ground. My last save was 3 hours earlier and several missions ago. Do I really need to go back that far?
