Fix: If you started the GPS far away without defining an entry point the GPS would automatically search for the closest point nearby. However, if that point happened to be in a different web of points than the one you were targeting, you would get the "cant reach destination" error message.
This has been fixed and the GPS will now evaluate a list of points until it finds the closest nearby that is also in the same web as the targeted point, or none if the targeted point happens to also be the closest.
