So I'm looking at the tame right now. I have JA or Nanjing units on, or adjacent to, each of Manchouli, Tsitsihar, Kiamusze, Harbin, Yenki, and Hsinking. According to the manual, as well as past experience, that should be sufficient to avoid the USSR mobilization penalty. Yet, I am getting hit with it every turn. It seems to correlate with when I replaced JA corps in some of those locations with Nanjing garrisons. It seems that the script should permit me to use Nanjing garrisons, but I seem to be getting hit with the penalty anyway.
