Hey Demi, If you wouldn't mind sending a link to the game over to Roll20.net/help as well as a screenshot of where you are seeing the issue it'd be super helpful. I suspect this is going to be something reminiscent to when it was possible to use the Freehand tool on the dynamic lighting layer. The curves for the freehand would result in thousands of tiny line segments that would reach a physical limit of the browser and dynamic lighting would glitch out. If we can repro this we can get this page logged for a patch to hopefully fix it in the future. In the immediate, it may be worthwhile to make a duplicate of the page and try messing with the dynamic lighting layer to see if it might be due to the amount of lines on the page.
