How to save vessel position, and then teleport back to that position?

[linuxgurugamer]

I'm working an old mod, AirPart.  Turns out the mod works, but has had a bug when changing scenes.

Parking a vessel at altitude, jumping to the Space Center scene and then returning will return the vessel to the same location, but at 0 altitude

So, digging into the code, I find that it does this to get the  current vessel position:

...
ParkPosition = GetVesselPosition()
...

// Following code from Hyperedit

        private Vector3d GetVesselPosition()
        {
            var pqs = vessel.mainBody.pqsController;
            if (pqs == null)
            {
                Destroy(this);
                return zeroVector;
            }

            alt = pqs.GetSurfaceHeight(vessel.mainBody.GetRelSurfaceNVector(Latitude, Longitude)) - vessel.mainBody.Radius;
            alt = Math.Max(alt, 0); // Underwater!

            teleportPosition = vessel.mainBody.GetRelSurfacePosition(Latitude, Longitude, alt + Altitude);

            return teleportPosition;
        }

So, in Start, I have the following:

                if (Parked)
                {
                    vessel.SetPosition(ParkPosition);
                }

and it doesn't do anything.

I tried as a test putting this into FixedUpdate():

                if (Parked)
                {
                    vessel.SetPosition(ParkPosition);
                }

and it ended up 1000km high.

I'm pretty sure this is something to do with the multiple points of origin, but no idea where to go.  Would appreciate a pointer or two, thanks

 

Happy  New Year
