Same thing happened here, first run after ~12 hours. The second i only played for 4 hours before seeing that Battania owned half the map and had 13k troops while everyone else was at around 1-2k. Just alt+f4'd and came to check if someone else have the same issues. They should definitely introduce some sort of coalition trigger, make other Clans abandon their faction due to dissatisfaction if they don't get a fief or claim independece if they gain too much. Maybe rebellions and civil unrest in conquered terroritories if they don't have a valid claim. Also the money thing would also explain a lot such as why the armies almost NEVER bring food and end up hogging all yours.
