Odd it doesn’t save the weather profile like it does for bush flights. If I alter the (static) weather it just defaults back to the preset:
UseWeatherFile=False
UseLiveWeather=False
WeatherPresetFile=.\WeatherPresets\BrokenClouds.WPR
I guess you can save the weather preset yourself and link it there in the save file, or just load it after. But indeed, a lot of work while the rest is still broken. And there is no way to save a live weather snapshot as a weather preset. Maybe one day.
