Well i undocked a ship while the ship was undocking and going on the takeoff rails i added some more takeoff rails when it undocked my ship got invisible and the accleration meter showed me infinite and the distance to the next sector showed me infinite too {F7415}
{F7416}
It showed me infinite to the next sector and infinite on the speedometer but i was still on the same spot where i was before.
And after relog it was still the same: {F7419} {F7421}
