First off, incredible work. Your mod has greatly increased the look for my and many other's games. The accurate states, particularly the mess that was Germany, takes dedication which I respect.

Now, there ARE some issues regarding Eastern Russia. Due note, I am not at all perturbed or in any way frustrated with this error. But I noticed that for some states, it uses modern Oblast borders. For example, Novgorod.

Now, normally this wouldn't be an issue, but it IS for Reichskommissariat Ostland. It's planned borders:

RK Ostland's planned borders cut through the lake in Novgorod, parts of Rzhev, etc. I, and some others possibly, are unable to recreate such borders historically accurate. RK Ostland during the war IS accurate, however.

RK Ukraine is also slightly different, but still formable. Here is it's borders:

In game using the mod, the general shape IS there, but Tambov, the state with the flat top that's poking out above the blue shaded area, is not as noticeable as the state next to it, Lipetsk, does not curve. I believe you can see the error here.

Again, this mod is amazing, and you did an incredible job. It just needs to be polished a little more.
