What?! I can't save my flight!?

[Rodlly]

A save feature will be great. In my case, I had lost already 5 long flights . ie: Tonight I was flying online from Bermuda to Chicago O'Hare
as American Airlines. My fs decided to be funny and gave me a screen saying :Flight simulator has encountered an error and needs to
close" we apologize for any inconvenience this may have caused". ........ Now I;ve lost another 3 hours of flight and have to start Again
