After a LOT of importing files I managed to remove all nationalty flags from the game. This allows you to do driver transfers without having wrong flags!
There may be errors in this mod, and if you spot any please let me know!
This mod is not compatible with any mods that edit the .erp files this edits (which includes the 2017 performance mod!)
(you can use this as a base for any of your mods as long as I'm credited)
Credit to @Meff28s for finding how to edit flags and work on this!
