Don't know if that's a bug but Slovakia has cores on "south slovakia" and "carpathian ruthenia" but doesn't have on "east and west slovakia", anyway cool mod.

When Red Russia win the Russian Civil War they just sign a white peace with brown Russia and Red Russia become really small, taking only it's core state when the war begins.
The same happen when red caucasus declare war on them and Red Russia win (red caucasus keep their core states)
When Red Russia declares war on Finland and win, they don't take anything and sign a white peace

The USA's focus tree isn't working. It just loads the generic focus tree.

when i try to launch the game with the mod it just launches the base game
