If Lighting.GeograpicLatitude is above ~90 or below ~-90, the sun and moon will flip as you go from one side to the other side of the map as shown in the GIF below. (ClockTime =2, GeographicLatitude = 92, Default skybox)
As my map is about 20000x20000, this is fairly noticeable and is quite annoying. I’m unsure if this is a bug or new feature to make the sun and moon react better to GeograpicLatitude but either way it’s broken.
Although I’m showing this in studio (as it’s the easiest way to show it), this does happen on the client as well but getting a decent GIF is difficult.
At sunset, this bug also makes my sun very thin and odd looking:
