Minor error in borders between the Russian and German Empires.
Shorty after his defeat, Napoleon's Poland was split up between the Prussians and Russians accordingly:

Lightest-blue is Vistula Land (Poland under Russia)

This means that the in-game provinces by the numbers of 11558 and 506 should be edited and placed under German control as to correctly display the borders which were determined back in the day.
It's very easily fixed. Already edited in my version of the mod and that only took 10 minutes of my time, so I hope you'll consider to fix this.

Has anyone else noticed any border errors?
