The issue with missed laps after a yellow-flag restart has been resolved.
It was a minimum lap time configuration issue. The combination of the lap timer clock pausing at the yellow flag (call-button press) and the long drift times of our cars after power is cut caused us to have a minimum lap time below the counting threshold. Ary and I confirmed this under controlled testing conditions.
I have reduced the minimum lap time for our default races from 3.5 to 2.5 seconds. This should take care of the issue. IF we find ourselves running another series where we experience a lot of cross slot activity (remember Trans Am and F1?) we can adjust accordingly if necessary.
