I really like the colors you are using. It is good for the eyes to not always see the same ones over and over again.

Good luck with AH. It will be a mountain task, since it basically is a disaster to be happen at any time and every way.

Also the Russian Civil War and Chinese theatre will be headache. So many outcomes to happen.

You are doing very good work with this as I see that you are using milestones. So Italian civil war, Two Sicilies etc. and derive the paths from there. If you would not use those, than it would be a mess. It is always easier to derive from a path later, than to not have a path at all.
