@FeelThere ArielNo, I haven't. Meanwhile I also started experiencing classic CTDs in random parts of the flight, however that issue stopped as soon as I performed a roll-back of Nvidia drivers. But landing issues persisted and seemed to be worldwide since similar crashes (with error message) also happened at KJFK (with default Asobo scenery) and also at EDDB (with Aerosoft scenery). I did some research and I found other people who experienced sim crashes on approach and they usually occurred after longer flights (3hrs+). I also read a commend hinting that some broken livery could be the cause because of higher traffic density at the airports. But this
a) made no sense since there were no crashes on departure
b) made perfect sense, since adding some freeware liveries was the only recent modification/addition I have performed
Now I have removed all those liveries and am gradually extending my flights. Today I flew for almost 2.5hrs and landed with no problem. I hope this trend continues.
And I'm also glad it's not KLAX to blame since I'm planning on buying FeelThere EDDF next week.
