your character file. you can go to the folder that has save files on PC by pressing a button on Load screen. or you can export the save itself on Android. it's called save1.json or similar. Edit it like txt files, find perks section
Sorry for this HELLA late response, but I've found the file thanks to your help, but even after I remove the "impotence" from the list, it still appears in the game. What should I do to remove it now?
You also need to delete the event that caused the impotence in the character, in the save files there is "StoryLine" after finding it, you delete the line that caused the impotence
