So I was having this great game as the Zunbil Satrapy (now shahdom) and had sworn fealty to the Abbablob to give me some breathing room to invade India. Then a decadence revolt happened and I though 'GREAT'. IN MY TERRITORY. So when the decadence revolt beats the Abbasids, what happens? Well I lose 75% of my kingdom. 3 GENERATIONS OF WORK UNDONE. Me set back to this tiny little rump state because they took all the valuable lands of my kingdom. Why? Seriously why does it work like this? Shouldn't they take the old caliph's demesne as their new demesne instead of taking MY land?
