ISSUE DESCRIPTION
When loading a flight with a Boeing 737 Max at KSTL with some custom weather [moderate rain and cloud cover around 10% and 4 knot winds] along with the St. Louis add on airport, it crashed before I could reach the tarmac in SU2 Beta 1.4.12.0.
I have had infinite and long loads many times, but this is the first time I have experienced a Crash To Desktop before the airport loaded.
It could be the KSTL Airport Add On.
