If you use my mod with a non-English version of TSLRCM, your game will crash, because this mod adds custom dialogues that do not exist in the vanilla game in order to prevent characters from referring to the player character by the wrong gender. The only solution is to play both KotOR 2 and TSLRCM in English.
I am not familiar with any of the non-English languages officially supported by KotOR 2 and TSLRCM, including German, so support for non-English localizations with my mod is not going to happen.
