I submitted a bug report but want to make sure I am not overlooking anything.
patch note:
You can no longer get 100% warscore from just fully occupying warleader unless warleader is alone in the war OR war has been going on for at least 5 years
my experience:
Only 3 years passed (I double checked). I got 100% war score occupying 3 province Tuscany, did not touch other coalition partners France, Burgundy, Aragon, Lithuania, and misc. I was Venice defending in a coalition war started by Tuscany.
