Supreme court - It lists one of its abilities as 'Free court house in every city', yet by the time this building is available, you have Pioneers, or at least Colonists, who both are able to build courthouses in new city builds.
Ergo, this 'free ability' is superfluous in nature. Please to remove or amend to a better ability.
Upgrade cost of a Transport to a Fusion Transport is only 20

, this is too low for a eternity speed game.
Please to amend to proper costing for upgrades. A Mobile Artillery => NLOS costs 1500

proper costing.
Liberation of Cities. - When you liberate a city to a Vassal, or Rebels it creates 2 or 3 garrison troops. But when you liberate a city to a non vassal, if that city is in rebellion, it creates no garrison troops, and doesn't create them on the change of turn. If the city isn't in rebellion, it will create 2 garrison troops for the new owner.
Please to enable the creation of Garrison troops for liberated cities to non vassal AI's, if the city is in rebellion.
Power receiver - It doesn't list the power plant in the city.
Please to enable the replacement of the power plant in the city on list of buildings.
