I completed a massacre mission for some pirates, went back to the marked station (in blue). There's a little exclamation point by missions indicating I can turn in or there's some activity, but the agent is not listed anymore nor are those turn in markers by anyone else's name. Since I'm new and don't know much I assume it's not a bug and there's something fundamental I don't understand. I only have combat missions so in my log so there's no delivery funny business I'm screwing up. What am I missing?
