Although I have the technology "Eminence" researched, the Diplomatic Ministry does not appear in the right menu of the colony screen and i am unable to build it. Is this a bug or is there a hidden preresiquite.The game does a very poor job of explaining what exactly you need for certain techs or buildings. In the tech tree says that if you have the Eminence tech researched you get that building. This is very frustrating since i planed my entire playtrough on that building adjacency bonus of +3 influence. Please come back with a reply or a fix if it is a problem. I only have the base game. No DLC, no mods.
