I'm playing as England in the 1444 start and kicking France's ass in the Hundred's Year War. I've gotten my wargoal objective and beaten multiple armies and have them blockaded. I had the option to make them give up a couple vassals, but I realized I could get my warscore higher if I continued the war for a few more months. Lo and behold though a few months later and I can no longer do shit. My warscore is higher, but now I can't even get a white peace because of the "relative strength of alliances" modifier. What the hell is this bullshit?!
