keithcurtis said: It should, assuming we are talking about the same thing. If you draw from point A toB to C and then back to B all on the same line, that will cause problems. Just closing a line (like making a square) should not. I'd test by making a copy and delete the lighting there. Then try putting in new lines and see if you get better results. I double back with every map I make because if you connect the ends of a poly, there is a light crack out the corner they connect. I also doubleback to create the indents in dotmm doors since most halls are 10x and the door is in the center. I only use LDL and i've yet to see this issue. My question then becomes, is this bug displaying itself ONLY in new lines drawn in the new version of roll20? Is the bug shown via a DM ctrl L'ing the tokens? Right now, none of my maps are displaying this lighting behavior. I'm concerned it will creep up and would like to know how screwed I am as dotmm is huge.
