I recently started a game as Castile. I've been in two wars with Morocco that I started with the Trade Conflict casus belli. In both cases on the peace screen there is no option to demand Morocco's trade power. What gives?
I can demand it from other parties in the war and I took trade power in an unrelated war against Tunis.
