This is a simple python script to remove nation livery restrictions on ALL modules you have installed (Official modules, third party modules, downloaded modules). Check

It works by finding all Liveries description.lua files and commenting out the line that limits the aircraft usable nations. With the version 1.1, I fixed an error with people that used shortcuts for the SavedGames folder.
