@pequenyo Since I already have my own damage simulation, ideally I would like Asobo's to be completely inert. However, since it's quite confusing that "Aircraft Stress Damage" damages the engine, and not "Engine Stress Damage", I have just fixed the metric that was causing the issue so that the Asobo system will only receive damage long after the limits are exceeded. I still highly recommend disabling "Aircraft Stress Damage" when flying with all of my aircraft; however, since I hate to see anyone's flight ended prematurely by an errant click on the pilot's storm window.
Thank you again so much for your helping tracking this one down! I was really losing sleep over it!
