This map can take up to 4 or 5 minutes to load on some half-decent gaming systems the first time you run it (but only a little over a minute once you've run it at-least once on that game version). Keep in mind the mod is 3.5GB so it can take a LONG time to download (you may want to pass up using the in-game browser and use your regular web browser to manually install it into the mods folder). Out now on the official BeamNG Drive forums.
