@johnnycat Good morning JC. Looking at your turn, you don't need to redo it. But two things:
It appears from how you placed your U-Boats around UK that you think they can block naval movements but that's not true. U-Boats/Subs & Transports don't block any ship movements. It won't matter during my Russia turn but on your J turn, use Edit to re-locate your U-Boats if you want. Or I can do it for you on my USA turn before I start doing stuff.
I feel like I need to let you know ahead of time about a few rules specific to China as I think it matters alot for what you do with your Indochina stack. So China is not allowed to move outside of China except for two territories which are Hong Kong and Burma. So my Chinese hordes cannot touch you when you are in Indochina or if you move to Shan State or Siam. But if you move to Burma or Kwangsi then I can.
Taking kiddos to school so will be awhile before I post my R turn but had a few minutes to type this out
