So I've been off for a while now, just came back for update 1.0.0 which has some really good performance not seen since the early early days of the game. I just sort of remember that at one point it was possible to message one offline colony to another and get resources from one colony, say zolarag's aluminum, to a human world and vice versa using I think empires and annexing one base with another.
I remember it being important that the messsage being sent from the smaller base to the larger base but I can't get the messaging icon to give me access to the other base.
It's been a while so I might have missed something about the steps to annex one offline base for another so could someone tell me how to do it. If it's impossible that would also be good to know and I'm currently doing regions so I don't know if it affects this
