At the time, #Ingenuity's flights occurred in the morning, before the rover started on its daily drive. Flight 24 occurred on Sol 398 when the rover was still at waypoint "Sol 387".
Got it? No? 😜

Sol numbers usually mark the end-of-drive Sol. Next morning is another Sol, but the rover is still at the old waypoint.

Another problem is that multiple waypoints during the same sol will all have the same Sol number (map + description).
