I'm missing something here. I'm playing as a count in France. I have a claim on a county, ruled by another count. I can't seem to find where it shows the crown authority for my liege, but it shouldn't matter because I modified my vassal contract to allow war declaration. For some reason, I still can't declare war to press my claim, it says I don't have a casus belli. The only war I can declare is independence from the duke. I don't see what could possibly be preventing me from doing this. My first thought is maybe a lifestyle trait? Was that changed?
