Not the Scenario, not a Sandbox -- I've just "finished" test-playing my Copperpot Orchards scenario (link below), and I want to upload the played park to the Steam Workshop . . . if there's currently a way to do this, I'm not finding it. I've seen a tutorial (link below) that says hover your cursor over the save and an Upload option'll pop up, but that hasn't worked (it's from 2016). I'm playing on Windows, and I've got a screenshot link below. Any help?
