This track is very nice and detailed, and light on resources. But, the AIs make a lot of mistakes, at least with the Mini Challenge. Moreover, the race starts at 7.30 AM when it is still too dark in the morning.
In .PLR file you can settings AI better and .GDB file you settings about clear /dark light of the track. Sure you konw to do...ok ? For me, this settings are nices for this track.
