Never Ending War

[Lewy]

I joined a Northern Crusade against the unlanded Fylkir without realizing the target was "---". Over 50 years have gone by and the warscore has been stuck at 75% since there is no land to seige. Since I joined the war I can't offer white peace. I have also tried assassinating both the Teutonic Grandmaster who started the war, as well as the Fylkir, but neither ended the war. How do I get out of this war?

As far as I am aware you can't. How they started a northern crusade against an unlanded character is beyond me though?
It might possible but you need to be inherited by another realm of your dynasty so that they won't inherit that particular war. This is not very convinient though and might not work

This same bug has ended my Outremer run. My relative (Grandmaster of the Teutonic Knights) started the Northern Crusade. He asked me to join so I joined the war and I didn't realise that there was no valid target.

Tried everything. Defeating the 300 man armies of the Germanics, assassinating everyone. etc
