Do you have the same issue if you follow the OP’s steps to reproduce it?
Provide extra information to complete the original description of the issue:
Update: i can remeber also where the long freezing, ground surfaces disappearance and CTD issues broke out: route Catania to New York, between ORBIL waypoint and the coast of Montpelier where i couldn’t see the ground surface of that french city, and, route Catania to London, at about fifty nautical miles from BUROG waypoint wich is on the Nederland shores North - Northeast from Amsterdam.
These routes aren’t possible to plan via world map on the main menu, but they were planned by myself through the MCDU of the A320 Neo (the plane i use for playing and my favorite one among all the others, the second favourite one is Cessna 152).
Giving these hint in hope to further help the developers in investigating the long freezing, ground surfaces disappearance and CTD issues occurred after 3 hours of flight.
