I see. So after we receive file from our opponent, (00France.txt for France, 01Russia.txt for Russia, 02Austria ... ) we put in in doctrine folder under Histwar...then go to doctrine editor, "choose the current doctrines" for his faction and then ours as well.
?..
As far as I
understand this system, once the host has saved the doctrine file in his folder you're good to go.
The game seems to always refer to the same file. Doctrine Editor is used to change the content of that file.
