O.k. - having reached the 800 day mark in-game the situation is as follows:
It is becoming a chore. I was awarded Tubilis Castle and I am vassal of the Asaid. Main quest failed because guess what - it had a 10 year timer. In the meantime I have managed to get all castle upgrades. Yet, I cannot leave Tubilis area. Why?
Battania has gobbled up Vlandia and western Empire while Khuzait have wiped away Sturgia and the northern Empire. Southern Empire holds both Castles around Husn Fulq and the City of Ortysia. Guess what? I am in a continuous state of war. I cannot do anything else than running around my castle whacking random SE or Battanian lords trying to raid my villages. And even my own liege does not keep peace even if he lacks the troops to wage war. Playing the Pokémon game with them I lock them away in my castle just to see them escape again and again despite 300 militia and a crack force of 200 T5+ soldiers garrison next to my 200 T5-T6 soldiers. Meanwhile my AI is lost while it cannot decide to take action like conquering border castles. Nope, it wastes armies running around errantly while small bands of nobles play the raiding game and are cought by Battanian armies rushing to lay siege to my castle (which never works, but that is another thing). The Aserai armies do such useful stuff like trying to take Usanc castle, but Ortesia/Garmator Castle is SE territory - it is not a border town or even trying farther up north. Bordergore is programmed and guess what? Those castles are awarded to a powerless lord and reconquered only 2 minutes later by the Battanians.
My game has evolved to "kill marauding army, sell stuff and prisoners, retrain lost forces, rinse&repeat". Oh yeah, and getting back my caravans that are regularly caught by minor factions or trying to do trade in enemy lands. I even cannot get all of them back when they escape prison. Nice of you going to Myzea after escape - how do I get there through 2 enemy nations? I can magically see where they are via wiki telepathy but am unable to send them a messenger to have them come to Quyaz. Frustrating. I cannot solve issues because either my faction's lords are somewhere running astray on the map or the villages raided or simply because I have no time for that, because I am too occupied to play the front-ex game and catch every minor lord and his little sister trying to raid the Quyaz area. Which is only temporarily as the escape my dungeon like it had revolving doors installed instead of iron bars. Any yup, they return again soon..with troops NOT being recruits, but mid-tier at minimum - wherever they got those in that short period of time.
So yeah...game is getting repetitive. I blame the AI for that as I cannot influence Unqid in conquering the "correct" targets and assign a powerful lord to hold them (me?) to just keep the spoils of war. Nope, it is stalemate or losing another castle in the east of the realm as I am not capable of bilocation
