I have noticed what appears to be a bug. Anytime I colonize a planet with a Vo-Dleh a D-4 will appear on the edge of the gravity well.
All of the descriptions of secondary effects for the elite colony abilities were out-of-date, now fixed internally:-
FED: Sends supplies and personnel down to the surface of the planet to create a new outpost. For a brief time tax and culture rates occur at a higher rate.
KLI: Sends supplies and personnel down to the surface of the planet to create a new outpost. Additional patrol ships are stationed around the planet and, for a brief time, structures are built more quickly.
ROM: Sends supplies and Reman work gangs down to the surface of the planet to create a new outpost. For a brief time, under cover Tal'Shiar operatives are inserted amongst the population to counter the effects of hostile cultures.
DOM: Sends supplies and workers down to the surface of the planet to create a new outpost. Additionally, free resource extractors will be built and the extraction rate increased.
BORG: Sends supplies and worker drones down to the surface of the planet to create a new outpost. For a brief time, planetary infrastructure can be upgraded at lower cost and growth rates are increased.
