[Sticky] Having problems with Steam's installed mods? Clean your mods in the most efficient way (example for Ark)

1) Check which is your default Steam Library in Steam -> Settings -> Downloads -> STEAM LIBRARY FOLDERS
2) Exit from Steam
2) Go into the Steam library you have and delete everything from steamapps\workshop\content\346110\
3) Delete also the appworkshop_346110.acf (Steam's workshop cache) in steamapps\workshop\
4) Go into ShooterGame\Content\Mods\ and delete every folder with numeric names and their .mod files (except 1111111 which is Primitive Plus)
5) Start Steam
6) Open Steam -> your profile's dropdown menu -> Content -> Workshop items tab -> Subscribed items and resub to your mods and wait for them to download (bottom center on Steam)
7) Start Ark and wait in main menu for the mods to be installed (bottom right with white letters)

Enjoy your freshly installed mods!
