So in the middle of the Hakkon empire warring with Elintor and half their lords being imprisoned by the Elintor(including the emperor) I led Aris Hakkon in a civil war and took the 8 lords not imprisoned and all the territory the Hakkon empire controlled.

Some days after I took control of the last Hakkon territory Elintor and Hakkon made peace but now I'm stuck as the hakkon lords have nowhere to respawn at and I can't complete the civil war. Am I stuck like this? Do I have to abandon the civil war and start all over?
