Aye @Apop85 This was just a quick fix and I didn't bother about updating formally. But as long as it works

Nice work but just a suggestion... update your workshop items insted of duplicating them ;)
1. Submit to your own Workshop item
2. Go to your workshop item inside the games main menu
3. click on update
4. click on the folder icon
5. replace the old files with the new ones in the folder which will pop up
6. return into the game
7. proceed to update your workshop content :)
