The bug still persists, it hasn’t been officially fixed. There are certain things you can do to reduce the risk of the bug occurring. Firstly make sure you restart the game after every flight, this boosts performance immensely, quit the game every time you finish playing instead of just turning your xbox off. Turn ai traffic off, increase your roll on cache from default 8Gb to 15-20GB, and try to fly to airports you have already flown out of before, this helps reduce performance that can be lost during the final leg. Make sure you save your flight while you’re in the air, before coming in for you final decent, you may wanna save flight, quit and then quit game, and reload. Use active pause to get autopilot set up, and then keep flying, I found this also boosts my performance.
There are a few other options to reduce the problem, I can’t remember them off the top off my head rn, but until this bug gets fixed, its all we can do for now.
