In my current game, I was dealing with the Comintern faction, which, in addition to the usual players such as Tanna Tuva, included The Netherlands, Dutch East Indies, China, and Communist China (I'm playing Germany). I reached late December 1941, and I was working on China, having forced the Soviet Union to capitulate). Interestingly, the other Chinese countries -- Shanxi, Xibei San Ma, Yunan, and Guangxi Clique -- never joined with China in China's war with Japan, and they remained separate and at peace in December of 1941 in my game. Then on January 1, 1942, I saw the map coloration for China's territories suddenly change color, and I discovered that China no longer existed; they had been somehow dissolved into Xibei San Ma, and I could find no explanation of how such a thing happened. Has this change ever happened to anyone else? What could be the possible explanation?
