hello I need help I am creating my mod and I would like to change the default name of the civilizations
example: the united kingdom becomes great britain if we change its ideology and I would like it to be called united kingdom even if we change its ideology

Go to the folder game > languages > civilizations. Open the Bundle.properties file with an ordinary notepad or Notepad++ (or another IDE). Search for Great Britain and change whatever you want. You should change from: uni_m = United Kingdom to uni_m = Great Britain (or whatever else you want)
