Workshop routes are reporting required add-ons which I already own. Any solution gratefully received!
So if you have all the necessary content required for the workshop route then you are good to go. You go to the Standard Tab and find the route where you find the content you downloaded and drive. You can also find what you downloaded in the Workshop Tab, select the Subscribed Tab and click on what you downloaded then hit Drive.
Isn't "Drive" greyed out if the WS Tab thinks you are missing requirements? Sure this is just one of the many broken elements of the WS feature.
I have found it greyed out a few times, but I've gone into the Standard Tab and found it there and drivable.
