well not exactaly, a staff member checked it out and he said he saw nothing, how about you download the map for your self and see whats wrong, he said to put a different terrainblock in it from another map but when I did that it just said Download it here ---> http://www.beamng.com/resources/death-valley.1090/
When you save a map it puts the Data in a Folder outside your map-folder. In your mapfolder there is only one .ter data. Should be multiple .ter data. Search through the BeamNG Folder for the place where the Terrain Editor put your Data. (Now i know why you made a Video lol)
