In vanila BTS, a civ that becomes a vassal ends wars with other civs. In FfH, the opposite occurs. I accepted a petition for a civ to become my vassal, and immediately three tother civs declared war on me. Two of these cis were my closest allies. This was shocking and doesn't make much sense. If a civ becomes my vassal, he/she should end their war with my allies, not drag me into the war...afterall, I am the new master in the relationship. I tell them to bring their troops home and stop pillaging my allies! <whip noise>
