I'm playing as Naoe on Hard. Toyotomi supporter.
Currently at turn 12, doing nothing much except being engaged in a push and pull war with Honda. Then the next turn, 8 different factions declared war on me. One after another. Those that declared war for no apparent reason, even Chosokabae, a fellow toyotomi supporter declared war on me. Not to mention this faction is halfway across the map and I have totally no qualms with them.
Is this some form of diplomacy bug? Or am I doing things really wrongly to have everyone attack me for no good reason?
