In my current playthrough of nearly 50 hours on the toughest difficulty setting, I finally created my own kingdom with 1 castle, 3 million Denars and over 1000 troops at my disposal. I'm kind of upset at the moment, though. While out taking a castle across the map, The largest faction in the game right now, Battania, declares war on me. I fought and defeated them on at least 8 different occasions and eventually they whittled me down to the point where I had to take my garrison out to stop one of my villages being raided. I lost that battle because of the horrible starting point on that village map that puts the defenders at a severe disadvantage and spawns troops in spaces they can't escape and had only 48 troops remaining in the garrison and 150 militia. I entered the diplomacy menu, spent the influence and declared peace. So, I start rebuilding my team, only to have Battania declare war in less than 1 day and immediately after, show up to my castle with 1000+ troops against my 210 man army and 200 troop garrison/militia. I attempted to barter for peace with the enemy general and in the barter screen it shows that the peace agreement is green and valid with nothing up to be bartered. The enemy general accepts the barter, though no peace is made. So, I try again and it's the same, so I offered 100k Denars, and the same response. No Peace... There is no indication whether I need influence or not to get that peace, I'm at -16 currently. I can't sue for peace in the diplomacy screen with negative influence.
tldr: I have to start my kingdom over from scratch because I can't get bartering for peace to work.
