I am flying Iraqi Airways flight 489 (Iraqi 489) from KBOS to ORBI in Training Server as a Boeing 777-200LR. I took off on schedule, the flight was going normal, until the game froze, but then resumed, but this time all the sound was gone. I could only hear the ATC. No engine noises, no wind, no chime, nothing. I’ve tried adjusting the volume and that didn’t work. I know you can fix this by leaving the tab and then re-entering the tab, but for some reason when i re-enter the game freezes. I don’t want to lose progress on my flight. How do I deal with this without risking my flight ending?
