Strange bug with workshop

My mods were working fine yesterday. When I started up the game today I noticed all the mods were gone. When I checked the GameData folder to see if everything is still fine and all there was was the default camso folder.

When I tried to restore the mods from the steamapps\workshop\content folder and restarted the game I noticed it deleted all of the other folders. Any reason for this?

Verify Game Cashe.

Did that, did not fix it.

EDIT: Came back today, problem seemed to fix itself.
