I'm currently play a huge continents map, BTS, Noble, Custom game (no tech brokering, no barbs, no random events). While at war in the north, I see hannibal's SOD gather on my southern border, I save then try to sign open borders. He agrees, and I think that gives me a 10-turn respite...but he declares war the turn after so I reload, and try trading some techs, he accepts but declares war the turn after Shouldn't there be a ten turn peace? Or does that only apply when the player trades with AI not the other way around?
