Saves often ignore state of flightplan ,the state ,speed & altitude of plane as well.Loading a save often seems to reset ATC just as if you’d restart the flight…
Saves also seem to fail to hold the data of the point you were at during flight
Here I shared an image(last one in the post) that shows the disconnect between IFR plan & ATC commands after loading a save Sim Update V (1.18.13.0) Bug Megathread - #438 by TripsyTipsy
Perhaps not saving logbook at all either

After loading a save,the ATC often is totally messed up as well.As if all progress was wiped during reloading..Would send you all back to the start in a long flight,even if you actually saved at arrival stage etc https://forums.flightsimulator.com/t/incomplete-save-load/272840?u=tripsytipsy
