I am playing as America on Prince in BTS. I am on a continent shared with Brennus, and we are very friendly. I am a culture leader. Then, Korea declares war on me from waaay across the world. Many of my cities go from being 100% american to being 40% american, 60% korean. And no culture from Korea is touching my borders, korea has sent no spies against me that I know of, and in fact, before that turn Korea had never even met me. Korea also has no land units or locations on my continent.

Has this happened to anyone? I do not understand why this happened.

Also, why is a culture declaring war on me the second they meet me from a different continent. It makes no sense.

I am using BTS 3.13

On your continent, was there another civ there a long time ago that you pushed off your continent or completely eliminated?

The only explnation I can come up with is that Korea is a colony. There's currently a bug where a new colony will "take over" attributes of a dead civ. Bhruic's unofficial patch prevents colonies from doing this (but once there's 18 civs/colonies in a game, no more can be formed).

I think that Korea is either a colony or a vassal of Japan, and it must have taken over the attributes of the Dutch, who I wiped out and stole all their cities from centuries earlier. So, it must have taken on the Dutch attributes.

How weird... Well, I rushed a few happiness producing buildings through slavery, thus reducing population and increasing long term happiness. It still stinks though, because now that city which would have been celebrating is barely manageable, and it will take centuries to become 100% american.

I will have to look at Bhruic's patch.

Thanks, this is almost gamebreaking it in effect lol.

Korea must be a colony, since colonies start off as vassals. If Korea was colonized somewhat recently, you could apply Bhruic's patch and then play from an earlier autosave before the colonization. This way, Korea will not inherit the Dutch's characteristics.

This problem extends into diplomacy as well. If you noticed, Korea will also have the dutch's diplomatic stances towards you and everyone else.

Thanks, now it all makes sense to me. Korea would have inherited the Dutch anger towards me, being that I basically wiped them off the map, which would make their master (Japan) mad at me as well.

Ok, now I got it... Thank you very much for taking the time to explain this to me.

I will try out that patch, and maybe replay this from a few turns before I destroy the dutch (swordsman with tower shields own any archers no matter how fortified). This is my first BTS game, so I want to replay it anyway to learn more about the espionage system, etc.
