Thanks to everyone's help on this forum I've finally completed my first scenario. However, I'm having trouble getting it published on Steam. I keep getting the message when trying to publish it that I have third party content in my scenario that was not downloaded from Steam. This is not true. All assets I use in the scenario were purchased from Steam. My scenario was made using the Cajon Pass route and also included some SD75's I purchased from Steam. I even tried creating a brief scenario using all default assets and got the same message when trying to publish the scenario. Would anyone here by chance know what is going on with this? Thanks!
