Just found 2 bugs relating to Tarckspeed in the scenario mentioned above.
1. The Trackspeed is randomly dropped for no reason and for less than 100m. This happend multiple times in a row.
2. After the 1/3 of the scenario the Track speed was capped at 60km/h and not raised above that. This caused massive delays and minus points.
