Fix VTOLs sometimes forgetting to rearm before flying off.
A VTOL would be waiting for a rearming pad to become available, but also happen to be covering a rearming pad, and get asked to clear off since it wasn't actually using that pad. The VTOLs would then get confused, and fly off as if it had rearmed itself already.
