I'm starting my first Roll20 game tomorrow and I've encountered an issue that I'm not sure whether it's a bug, or I am doing something wrong. My game has six players (seven including myself). I can see them all on the front page for the campaign. But when I launch the campaign, one of the players doesn't seem to exist within it. I've created up the characters and assigned five of them to their five players - but one player just doesn't appear in the list that the others do. Is there some setting I need to change, or something I am missing?
