So I'm just playing normally, I just took down Denmark (they weren't guaranteed or in any factions) and suddenly, a few months later, France declares war on me randomly, no ultimatum, nothing, just France randomly declaring war on me, next thing, Italy does, and then for no reason so does Russia, and then Britain joins them for no reason? I just spent 2 hours doing focuses and now I've wasted all that time because countries randomly declared war on me, I'm so angry right now.
Why did this happen?
