Industrial map broken

So, i was exited to play the new map and drive the new roamer but then suddenly, oh no! The ground is gone, buildings, trees, barricades, all there. but no ground. i fall right through. I have deleted all my mods, i have changed the user folder thingy, i have restarted the game many times, i have verified games integrity files thingy on steam and through the game itself,i have even edited the startup.ini file. safe mode works, i just want to get the map to work on the normal game. Please help!!!!!!

 

sorry for not responding sooner, i was busy all weekend. my user folder is just called "BeamNG User Folder"
