My fix last patch for livery uploads ended up breaking all workshop uploads. This should fix that.
Also, some issues with making campaigns where multiple missions use the same workshop map have been fixed.
v1.9.4f1
General
- Fixed: workshop upload whitelist caused all workshop items to upload incorrectly in 1.9.3
Mission Editor
- Fixed: Creating a new mission using the same custom map as an existing mission would delete the map from the campaign
- Fixed: Deleting a mission using a workshop map shared by other missions would delete the workshop map from the campaign
