I just got dragged into a war between Crimea vs Lithuania and gang out of the blue, at first I thought it was because I was defender of the faith so I reload and ditch DoF, bam war still declared around the same time in the original game. I looked and looked for the cause because I have no diplo relationship with Crimea. Turns out that my vassal Georgia decided to take Crimea as their protectorate and that's what caused me to enter the war... I'm under the impression that Vassals can't have any diplo relationship with other countries? how is it that my vassal can take another country under their protectorate? Is this a bug?
