I have followed the quest marker for the quest star-crossed troopers to locate Hayes’ grave. I have found it and it is highlighted blue when I interact with it but nothing happens. I can examine the head stone but this doesn’t tell me much and doesn’t complete the quest either. What are you meant to do to complete the quest?
You need to make sure Nyoka is in your party before you go there. Go back to your ship and put her in your party. Once you get there, you will be able to interact with the grave to complete the quest.
