Doesn't it look like Just Cause 2, that is where I got the inspiration for the map, and it's released sort of past the point where I could have changed the name.
This map shouldn't be any different than any other map that people made in the editor, so I don't know why you are having this problem. Did you try restarting the game and loading the map again?
It is the Speedometer mod, I believe it is in Content Creation, Programming Nope it isn't, it is in Showroom>Utilities and Programming
I am getting this same error on this map. It was working for days but just now today started giving me that error either immediately after launching the map or when trying to change car or drive.
