if you downloaded a mod then decided to remove that mod it might’ve broken that save especially if it added new fetishes the only thing i can think of if you did this is to make a new save or go to a save when you never even had the mod enabled (be aware this also includes if you disabled the mod as well)
if it persists then i’d say to troubleshoot by disabling one mod at a time to see if the error persists when it stops make a note of it then re-enable the other mods, other than the broken mod, then either make a bug report of that mod or just play like normal, up to you
