Is this a bug or it isn't yet implemented in game
They aren't meant to. My Colony and Antiquitas are both meant to only work when they are open. Otherwise, there is a very big problem with running out of resources when left too long. I should know, done this a time or two by accident just leaving the game running and going to bed.... My Colony, Reptillian race and ran out of Uranium.. meant no power and not enough money to buy more to get things going again.
