Loading a map takes me back to the main menu.

Recently I've encountered this problem a few times where if I load a map, it just takes me back to the menu. The loading screen doesn't even start. This has mainly happened with Mammoth Valley. I've tried restarting the game, restarting my pc, redownloading the map and clearing the cache. Even with only having the mod of the affected map installed, it still brings me back to the menu. Any help would be appreciated!

 

If it only happens with Mammoth Valley, maybe it's just broken and it's not a game problem.
If it happens with every BeamNG maps even official ones, try to clear your cache in deep mode.
