Unless there were errors during the application of the mod, I am unable to determine the source of the problem. If all steps were followed correctly, then folder permissions become a possible source of problems. The patched mod system should report any problems opening or saving files.
The Strive Discord (https://itch.io/t/284398/discord) is a great place to resolve tough issues as we can share a lot of information quickly. Since simple reminders were not enough to fix it, the next steps will involve verifying each step and aspect of the process . Basically it involves checking the mod folder path in-game, the folder names and paths for the mod files and replaced files, and opening script files to verify that they have indeed been altered correctly.
