Navigation data base goes through 28 day cycle. Always changing, revisions to airways, arrivals and departures, to airports. Reason why two or three pilots are verifying flight plans against FMC loading. Waypoints that have same name can be found and corrected. Standard procedure. You think that all the waypoints on the planet, won’t be duplications. Let me throw this at you. Pronunciation with accents cause similar waypoints to be confused. Reason why pilots and controllers verify spelling of waypoints. Life is easy. Let the trained experts do the job. Arm chair pilots stay home. Good flights.

This was caused by NATS failure to properly test their flight plan program, if an invalid flight plan is processed it won't cause the system to crash. In the words of President Trump "where someone will be fired".
