The path should look something like Drive (C:)->Program Files->Steam->steamapps->workshop->content->435150 Go into your Steam directory and find the workshop folder for DOS:2. This is probably not strickly necessary, I just wanted to tidy up
I manually went through my Steam workshop subscriptions and unsubbed from everything that wasn't for the DE. I forced Steam and the game to re-download all workshop content from scratch. Alright, I think I may have found a solution, it worked for me anyhow.
