Before you cleanup your subscribscription folder, you should unsubscribe to all workshop blueprints.
Before you do so, I suggest to create your own private collection and add there all your favourite blueprints for easier management.

If you already have a private collection for your subscribed blueprints, then you can skip down to the "IMPORTANT NOTICE".

To create the new collection, go to the community Hub / Workshop and choose "Browse" > "Collections".



Then click on the "Create Collection" button and fill up all the needed fields.



After you created your collection go to worksshop and browse you subscribed blueprints, then add them one by one to your new collection.

IMPORTANT NOTICE: Before adding any blueprint to your collection, please check the blueprint's date. The upload date or the last update should not be older then 3 Months!
If you already have a collection with your favourite blueprints, please check all your blueprints for up to date version. Do not use any blueprints older than 3 months.

After you have created your blueprint collection and added all your favourite blueprints there, you have to unsubscribe from all subscribed items.

Go to Community Hub / Workshop and choose "Browse" > "Subscribed Items", then unsubscribe from all blueprints.

Be sure your game is not running.

Go to your Steam Library folder and delete the Emprion workshop folder.
Usually you can find it here:


Delete the "383120" folder inclusive all subfolders.

If you don't know, where your Steamlibrary is, go to Steam menu > "Steam" > "Settings" > "Downloads" :



Click on "Steam Library folders" to see the details.

Now this is what you created your private collection for.

Go to your collection and click on "Subscribe All".

Wait until the downloads are finished.

Then check your game for showing up workshop blueprints.

Hope this worked for you. :D
