The title says it all. I offer to join the war of an independence rebellion (I am the King of the Reach, pre-iron throne) against the Ironborn-ruled Kingdom of the Trident. Unfortunately, they are already severely at a disadvantage, and I could not get there in time to help them win. When they surrendered, I became a vassal of the Trident, and I'm almost entirely sure this is not working as intended. Is this fixable, or do I just have to be more cautious about joining these types of wars?
