This mod should fix how countries always follow historical focuses even if non-historical focuses are turned on.

We need fix so that every country can create a faction. ATM counties can only join either entant or cental powers (or Comintern if CCCP is in existens).

Make the border with Russia and Germany correct, like the HOI4 devs did. Assign the provinces to the correct states please.

Thank you very much for the quick reply. I was not aware you were having troubles, I was just puzzled why I see no reaction to people asking for description. Also a bit frustrated as I am checking this mod over the last few days with no changes. Sorry if I come off too harsh.

Looks interesting, will check it out :)

Steam keeps cutting off descriptions.

I’ve posted the todo/status list which is what most people seem to want. If Steam keeps cutting it off then there ain’t much I can do.
