same problem.

Same problem with PC-24.

I can confirm that as of August 2026, the error is still occurring. The program freezes immediately.

I tested this in both the PC-12 and PC-24 and had no issues importing a flight plan, deleting waypoints, deleting the continuities those deletions created, adding new waypoints, deleting those, deleting those discontinuities, etc.

Are those having issues seeing this in Career, Free Flight, or both? My testing was only done in Free Flight.

Same issue from time to time with pc12 and pc-24. When you start playing with the avionics on MFD, you pray that system don’t crash. Difficult to reproduce but it has to do with modify the waypoints in the fplan

Yep I can confirm this is a reoccuring issue for me on the PC-12NGX. Extremely frustrating, especially after migrating to msfs2024 a few months back in hope for more stable flights
