Myself and a friend both run games. Hers Fridays, mine Sundays. Both games contain the same players as we are a group. There was one player in both of our games that left due to not fitting the overall dynamic of the group. He no longer appears in the player list for either game. As far as Roll20 is concerned, he is not part of the games. However. During one session of my game a few weeks ago, he appeared in the game(Name at the bottom of the screen showing all the people currently actively in the game). But he still wasn't in the main player list for the game. I figured it to be a weird bug and nothing else. Since then, he has appeared in my friends game as well. And then, recently, he appeared in both of our games and rolled. So somehow, despite not having permission for our games, not being in the player list for our games, he is still able to join our games and roll.
