Expected result

Either v->dest_tile is updated upon relocation, or some other more elaborate method needs to be used to reflect the actual location of the buoy.

Actual result

This bug is deeper and has nothing to do with the pathfinder. It's about buoy location. The buoy is removed and moved to another tile, this doesn't update the v->dest_tile of vehicles.
What happened:
The previous location of the buoy was valid, but then demolished, and rebuilt to a near location, reusing the same WaypointID value, but with a different location. The old place was then raised terrain and became waterless.
The pathfinder is given the old location, and the high lvl pathfinder finds a patch with no water, hence the label 0.
Low level pathfinder doesn't even get the chance, it fails right away in high level pathfinder with a size of 0
would probably be given the same erroneous location, since it's also m_destTile = v->dest_tile;

Steps to reproduce

1. Build a buoy.
2. Build a ship.
3. Add order to go to buoy.
4. Start ship.
5. Demolish buoy.
6. Rebuild buoy near the old location, reusing the same WaypointID.
7. Raise terrain on the old location so that it becomes waterless.

Ship is lost!

ship 2 is lost because buoy was relocated.zip
