You are correct about the Crusade thing. I saw that all the civs where in it and I freaked out because the Civopedia says (I think) that Civs can't engage in diplomacy w/ enemies while in Crusade. I later realized this wasn't the case. Then again, I could be getting confused from all the FFH2 daughter mods I've been playing. Orbis is certainly the best of those daughter mods.
