Okay, good to know that you are calm about this.
Something strange also happens when you research electricity, regarding foreign cities you have dumped into, that I have always wondered about. Before the tech, foreign cities that you can "investigate" are dark on the map, and don't reveal any tiles in your line of sight (but you may still investigate and see the units inside the city). After the tech, cities are "revealed" in your line of sight, and also begin to reveal the 8 tiles surrounding the city as well. Here's a picture that shows what I'm talking about.The tech that prevents losing contact is Electricity, because it also represents telegraphy. It has been like this ever since the original RFC, but I agree that it's not properly documented. Maybe a special effect entry for the tech and a loading screen hint wouldn't hurt.
I'd have to check what exactly is causing that but I am pretty sure that Electricity somehow unlocks that espionage effect for free. Not sure if it's a BtS or RFC thing.
The things you learn about this game after playing for over a decade...IIRC it's a BtS thing (I haven't played vanilla civ in a while) and I remember somewhere being stated that Electricity unlocks that.
I thought it was Satellites, but, yes, it's a default feature from Beyond the Sword.IIRC it's a BtS thing (I haven't played vanilla civ in a while) and I remember somewhere being stated that Electricity unlocks that.
Another thing: The Philippines are outside Catholicism's historical area. Whenever I conquer or settle it as an East Asian civ, that religion either doesn't spawn or goes away.
Speaking of which, maybe Catholicism and Protestantism should have a grasp in southern China due to European colonization. But there should definitely be Protestantism in Korea, as nowadays 20% of South Korea's population is Christian and especially Protestant.
Should it be though?
I think the Spanish conquest was a bit of a fluke, I don't think it was predestined to happen. Honestly I don't think even think it should be in Spain's historic territory as the conquerors events already assures AI Spain will go there. But there is no way in 3000 BC or even 600 AD that the Philippines becoming a Catholic country was a given, due to its location.
