In the Downtown Career Scenario (playing on Windows), the existing Vendors' Work Roster assignment field (in each vendor's Employment Tab, also in the Park Management > Staff tab) doesn't have a free roaming option. New-hire Vendors do, the existing Mechanic and Janitors do, but not the Vendors.
Although most of the Career Scenarios were added prior to the Staff Features in the November 22nd 2017 Anniversary Update, Downtown is the only one I've seen this problem in. This persists when loading a save of the Downtown Career scenario into the Scenario Editor. Since I've been working for a while on a Custom Scenario based on Downtown, and just spotted this while I was reworking the Rosters, it's particularly frustrating. I wanted to keep the existing vendors -- any way to fix this other than fire 'em all and hire fresh?
