Hello, I wanted to make it easier to build maps with things like trees and other round/elliptical objects, so I wrote a script today that allows the GM to draw a circle on the dynamic lighting layer and have it automatically replaced by a polygon approximation of a circle instead. The drawing works correctly-- or at least, the new polygon appears in the correct location and the circle is deleted. When I use a character to check it, however, the actually area that's blocked is offset by the diameter of the circle, always in the same direction. Any ideas what could be behind this?
