I'm using CORE for the second time (great mod!) and have noticed that there is an event about Russian-Japanese fighting at Khalkhyn-Gol river in summer 1938. Playing as Germans I saw that it led to a full-scale war between these two, lasting quite long. So, my question is: is there any event ending this war? If so, what triggers it? Or maybe playing Su or Japan I could only end this by sueing for peace treaty?
