I am stuck and can't progress the Suthsexe arc. I don't have any previous saves to work from, either.
After completing the mission "Reaver of the South", Soma is invisible and I can't interact with her. Everyone else here is visible and I can interact with them:
After this, there is a quest to take a camp, and then 3 quests, one of which includes this NPC Soma, called "Scorched Earth", with the task "Regroup with Soma". I can find the location in the world, but since she is invisible, I can't interact with her. I see the quest icon above her, but she is visible. And so I can't continue the Suthsexe arc.
