Continuing a saved flight

Whenever I save a flight (even if I make it the default flight) in mid-air, the aircraft settings are lost when I load it again.For example, on a long flight, if I save the flight and then reload it the next day, the engines will be off, the route I loaded into the FMGC will be lost, and the aircraft starts flying back to the original airport! (I mostly fly Wilco Airbus Vol 2 a/c.)Can anyone tell me how to save a flight and retrieve all the aircraft settings? Without this functionality, I'm limited to very short flights!Thanks
