I know the editor is in the beta stage but has anyone made any activities both freight and yard for the route. If you have is there any way to post them online for people to download and add to the game?
I presume you mean PC Editor so unfortunately that isn't possible. As for scenario editor, it's just a case of looking on Creator's Club.
Only by using the unofficial editor. Last time I checked the official one didn't have the cooking feature.
No, there are unofficial fixes for the cooking issue for the official editor. Look at the editor forum.
