Problems creating new country tag
So I was trying to create my own unique Rome tag because why not? Figured out how to do a lot of the basic stuff on my own. Got my country files set up (Rome.txt and RME - Rome.txt) and located in what I assume are the correct areas. Added the country tag to the countries.txt list. Added some real quick, basic custom flags. Made a new line for localization. Went back into my save game to test it out by adding provinces to it via console command and it doesn't recognize the country tag. Not sure what I'm doing wrong here. I am using GFM and all the modifications I made were to / in the GFM folders (which I can easily undo if necessary, I made duplicates of the base files that I edited just in case).
I would also like to turn this into a very simple decision so I can just pick a country like Italy or France and quickly change it to Rome.
