When I got up to the mouth of the bay, I turned around and followed
the bug back south. [...] my destination was 5,900 miles distant, and
the time to
get there was 84 hours.

When I got home, I scanned out and out on the map, to find that my
waypoint was now located in the Andes on the Argentinian side of the
Chile-Argentina border.

What happened?

What happened was precisely why I am so vocal about paper charts and
against reliance on this newfangled gizmo thang. (and horrified at the
thought of central computer control of airplane systems)

I find I make many more mistakes than than these newfangled gizmos that have
been around now for 15 years. What bothers me is pilots relying on old
technology when they could increase their situational awareness many times
over if they took advantage of current extremely reliable technology.
