But,for the Kercyx mission, I just replace my files (without changing json names) with original and it works (just Ruddy pack can't be installed, English or French))
If you replace the files, you lose English and it is always French. Modders need to use translatable strings so the game can select the translation depending on the settings.
Was my meaning...(of course,if you replace my files with others,you'll have the translated json language) but I really couldn't install Ruddy pack whatever the language
