Last night I had no issues with Roll20 and was GMing a campaign with 0 issues. Today I keep trying to set up the map for my next game and every time I draw something I can't delete it. And whenever I try to use the polygon/line drawing tool to map out buildings I can't deselect it or even finish a shape. I am using Google Chrome. I have tried numerous things to fix it and have gotten nowhere. Any help would be appreciated.
