Dont know whether its a bug or intended feature but its quite annoying to see some random city somewhere far randomly join your faction causing u war with others. I was playing as Sicily , destroying Carthage ,suddenly some city in Nothern Iberia ,apparently greek ?? (i always thought Massila was the last greek foothold) joins my faction ,causing my long term Roman allies to wage war on me. No warning-nothing.
Please enlighten me , how the hell do i get rid of it , i dont feel like fighting my allies because some random idiots decided to join my cause.
