Airfield full course. When I select this track to test any car, I can do it normally. But when I try to restart, the game stay loading forever http://youtu.be/wEDRo-e22O0
Same thing happens to me.
It must be a recent issue. I have tested there a bunch of times in the past and restarted just as many but that would have been approx. 2+ months ago. Have not been there since.
