Hi Erich! This is almost certainly because the player built their character in Roll20 Characters. This has been causing a bit of transition confusion. When a player uses Roll20 characters and imports it into a game, they retain ownership over the character. A GM can duplicate the character and do as they wish with it, but they cannot reassign it. If they delete the character, it is automatically sent back to the player's Roll20 Characters repository. With Roll20 Characters, players now have more agency over their character sheet.
