does not work, but it works if you add this file to \Documents\Neverwinter Nights\development

Hello, well, I just checked and the correct file should be uploaded. It may be for some other subscripted item, which can collide, or something in your override.
Here is the link for single file:
https://drive.google.com/file/d/1tsgZSERqYVB3EFJtBH4YcdbVWspIlzHZ/view?usp=sharing
download it to your override directory and if you can, also check the workshop files
(path should be something like: c:\Program FilesSteam\Steam\SteamLibrary\steamapps\workshop\content\704450\1596894295\)
Does anyone else have the same issue?
