Looks like thunders aren’t present in FS.
Last night there was sewere thunderstorm near LQTZ, west from LQTZ to be more precise. I loaded a flight at LQTZ, waited about 10 minutes, not a single lightning flashed.
That same thunderstorm passed near LQTZ and over my town. It was like in war zone, flashed and thunder all over the sky.
In FS it was very cloudy, but nothing else.
