Now every time a war starts by any reason all the Great Powers will get involved. Doesn't matter why, they will get involved and will strife until one side is annihilated. Wars with almost 500k units on each side aren't uncommon (I've seen three in my game as Spain, all caused by the Pope for a silly goal).
It's causing a small problem, because no one can declare war on anyone or they'll call Russia, France and three other continents at your choice against you.
