'not showing up on the map' is, unfortunately, a very vague and nebulous description. I'm going to ask some questions that will, hopefully, get us more information and help you troubleshoot your issue :) First off: What webbrowser are you using? Roll20 only supports the latest public releases of Firefox and Chrome. If you're using anything else, please install one of those and try again. Secondly: What happens when you do this?
