First of all, thanks to keep this mod and doing changes over it, i beg you to keep it !
I state that I've read changelogs of 2.6 but I didn't try it yet, but i want to report a bug which i experienced, no idea if you ve ever looked at it or someone has reported it.
I was with kingdom of Denmark as vassal, sieging with marshal and others vassals a city, after siege was won, kingdom of denmark kept sieging themselves and fighting eachother.
I also experienced the red messages with some error about creating AI Lords, or something like that, next time i will share more details if you don't understand what i mean.
Last i remember, there was a party with 300 men as size, prisoner party ( i guess ), they were following me while i was with all others vassals. When they approached to me, others vassals around me of my same faction didn't join the war, as i was expecting.
