Never used diplomacy much until recently. I can't figure out how to even start relations with a minor faction. I send in an envoy ship. It gets shot at and destroyed. Can't setup an embassy, only can use diplomatic immunity function. Where does Goodwill come in?

I'm not sure that I am even looking at minor faction planets. Names of the races on the planets are things like Herdunt Guard, or Kilebi Scabites, etc. Hovering over their planet i see status markers such as 50% allegiance, population, planet health and usually a negative tax income rate. This is very early in the game so i don't think they are allied with other races yet. The only difference I've noticed since installing this DLC is a lot more of these entities on the map

I am currently playing in the E4X mod with minor factions enabled, is it possible this DLC doesn't work in this mod?

Any advice appreciated.
