Saving a flight in fs 2020, when you reload the flight, the flight plan generated at the beginning disappears. is there a system to solve this problem?
Thank you

The functions provided by Asobo to save and load flights (and also flight plan)s are still not 100% working, and are documented as 'NOTE: The current status of this function is NO ERROR, NO RESPONSE.', So not much can be done about this at the moment i'm afraid.

Although the plan should be saved and loaded with the flight, you could try explicitly loading the plan again after loading the flight to see if that works.
