PRC FAQ
Q1.) What is this switches thing?
A1.) In your My Documents\Neverwinter Nights\override folder should be a file called personal_switch.2da. Edit it in notepad and change the numbers labeled 1 to 0 or otherwise as desired. Once you start the game again, you can force the changes into a current game by opening the PRC Options menu and picking "1. Alter code switches", followed by "2. Read personal_switch.2da and set switches based on it's contents". Verify that it replaced the switches as given.
Q2.) It isn't working.
A2.) Navigate to "Steam\steamapps\workshop\content\704450\1647391559\override", and delete the personal_switches.2da there. The game gets very confused if it is in more than one place and the Workshop files are loaded after the Documents files.
