[Peppie84]

if the FlightCore.GetTotalThrust() returns 0 because my engines are deactivated the Flightcomputer will be crash by the calculation of the RemainingTime, only on activated Queue-View. See: http://i.imgur.com/8qWv5a2.png

And this Exception was thrown:
[Exception]: OverflowException: Outside range [MinValue,MaxValue]
