We're currently working on fixing an issue where mods are placed into incorrect directory. As we're working on patching it, here's how to fix it manually:
- subscribe to the mod normally
- go to 'SteamLibrary/Steamapps/workshop/content/<NUMBER>'
- move everything inside 'mods\mod<NAME>\content' to a newly created content folder if it does not exist
- delete everything else (the "mods" and "dlc" folder if applicable) inside the steam workshop item folder
