Hello, just started playing this game after having it sit in my CD case for a good many years. I have a question that I had absolutely no idea how to search for since the question isn't Google search friendly. I have been playing a game with what I thought was 6 other factions (The game is currently now at 1914 AD, so for 5914 game years it was ONLY 6 others) and the entire game map revealed except for a very small portion of ocean and the artics. I am just about to finish satalite research so i can see the entire map and all of a sudden I get a "Hi are you friend or foe?!?

" communication from a civilization that never existed before. I do the usual "Yup Im a friend

" response and 5 cities that were previously one of my allies change into a new color and this new civilization has taken over them and become a vassel of my allies.
Now I know this civilization never existed before because the cities they now own were my allies. The civilization never participated in the Apostol vote, and now that the civilization exists its in the Apostol vote at only 3 votes. Where the hell did it come from? Can you create a new leader and appoint them as a vassel over territories you no longer want to deal with? Can a civilization literally hide on a small island with only one town in a less then 4x4 fog of war block and literally never join the Apostol vote, never make a new town, never build a ship to explore, never attempt communication with anyone, never leave the island and never be seen until the 1900's?
