Something is definitely off with the night lighting after light shafts update. The easiest way to see what's the problem is is to load "night showcase" and see how lighthouse lights flickering in distance. It's not like that in a stable build. I'll provide some gifs and pictures below.
Another way to see what I'm talking about is to spawn a car at night, turn on headlights and then use deletecollection or hideObject on the car. Check screenshots for more info.
