It’s like the flight plan that was created in the world map doesn’t get loaded in its entirety, causing some break points in the flight plan, missing lines, etc.
If I use the developer version and the world map to create a full flight plan with departure gate, SIDs, STARs, Approaches, up to the arriving gate. The full flight plan and their waypoints are always get loaded properly, and I never had any issues. Never flyback waypoint and ATC always follows the flight plan. So I always depart and land without any flight plan issues.
And I use navigraph navdata update, so all the waypoints, SIDs, STARs, and Approaches are all coming from the navigraph navdata even from the default world map flight planner.
