Changing faction names

[AndariusHaliusScipio]

I tried this myself. I extracted the Localisation file, found all the "faction_screen_name" entries, and changed them to my fittingness. But this change doesn't show up in game. I tried putting it in the data folder as a mod pack, I tried adding its name to the script file, but nothing changes the factions' names. What is wrong here?
