1. This is the overall view. Using Star Chandelier as Ceiling Light, and the white wall behind is Stage Panel.

2. Ever since I bought this house few months ago, I saw a tiny scratch that was being reflected from the star chandelier on 1st floor. (The scratch isn't on the stage panel). At first, I checked if I had anything blocking the light, but even if I remove the wall(stage panel), the scratch is still reflected to the floor.

+ The photo above is the same scratch I can see. Nothing is placed around it or blocking the way.

+ This is how the scratch looks like when I block it with other furniture from indoor furnishing menu.

3. Then I tried changing to different ceiling lights. It came out that that scratch doesn't show on other ceiling lights, so only a problem with Star Chandelier. I asked my friends to see (to check if it was any problem with my computer), but they are also seeing the same thing.

Please check if there is a problem in shadowmap from this light.

This might not look like a big problem.. but this distracted me for few months since this place is being used as photo booth. I'd appreciate it if this bug can be fixed. Thanks
