Draw Shape - circle tool for lighting

Is this intentional, or a limitation? When I use the ALT key to force the Draw Shape tool to create an oval or circle, and then use that shape on the lighting layer, the result is a 3 sided figure  that does not block sight in one direction (usually SW unless rotated). Example below: I have copied the lighting layer circle to the object layer for visibility.

Known limitation. <a href="https://wiki.roll20.net/Dynamic_Lighting#How_to_Add_Light_Obstructions" rel="nofollow">https://wiki.roll20.net/Dynamic_Lighting#How_to_Add_Light_Obstructions</a> Note: Presently, circles drawn with the Circle Tool do not render light blocking correctly. Instead of using circles, create a rounded shape with the Polygon Tool. You'l just need to draw a&nbsp;hectogon. ;-P

The Dynamic Lighting Style Guide page warns against using circles : A circle drawn on the Tabletop isn't represented by a series of segments, instead, it is a vector calculation that draws a spline between four vertices. Since there aren't any true segments used for a circle shape, there is nothing there for the Dynamic Lighting system to reliably ray-trace as you would expect regular linework on the Dynamic Lighting layer should. If you need a circular shape for your Dynamic Lighting, we recommend drawing it out as a rounded polygon instead. Since you are a Pro user, there is a script floating around here available in the One-Click Library that will automatically turn ellipses into polygons:&nbsp;DLEllipseDrawer.

Of course... I've got a script for that...&nbsp; <a href="https://app.roll20.net/forum/post/5582304/slug%7D" rel="nofollow">https://app.roll20.net/forum/post/5582304/slug%7D</a> =D Edit: I hadn't seen the DLEllipsDrawer before... I think mines a little easier to use, but either should be fine.
