I am experiencing a problem with the driving surface of my track. I used the expand surface method for creating my pit road, and now I am experiencing a rather pronounced bump on the inside of the front straight right at the start of where I drew the track (the first point). I tried to just lower the surface, thinking maybe it would help. It did not. It more or less makes the track unraceable as it has fliped open wheel cars and almost rolled closed wheel cars. Ideas on how to possibly fix this?
