I’m playing on Series S - I had my weather preset to light clouds. I went into photo mode and changed the weather several times to take pics. I exited photo mode and the weather had been reset to clear. I’m not sure if this has been reported or logged yet but thought it best to mention. Edit. Well this is weird! I went back into photo mode in the same session and the weather jumped from clear to my preset of light clouds. I exited photo mode and the clouds just vanished.
Something similar happens if you save a game with a custom weather preset. The saved game will have clear weather.
