Routes often truncated leaving just four points

FlightAware General

On https://flightaware.com/analysis/route.rvt?origin=RCTP&destination=KSFO
we can see that there is some error happening, causing
all but the final four items to be thrown away. Leaving for example
just

3800N/13000W ALLBE PASIF PIRAT2

very often.

It cannot possibly be one airline to blame, as the same error happens a
certain percent of the time regardless of airline.

Also when it happens, it leave exactly four points. The first is
Lat/Lon, and the rest are waypoint names.

And on the map on

we see the ‘planned route’ dashed line has a big turn that reflects data
that is no longer anywhere on

Visiting an average upcoming flight, for example

on an average day, say today, the route listed just shows the final part,

Route	3900N/13000W DACEM PAINT PIRAT2

But the map shown reveals more to the story. A crook in the route, here,

m20230607T054937

proves that FlightAware has indeed received the complete flight plan,
but a bug in the software just truncates the route listing to just a few
final reporting points.

My analysis shows only once every few days does the data make it through unscathed,
