In Lego Star Wars the Skywalker saga you can use a duplicate glitch. To execute this glitch, use the mandolorian as the first character, then go over to third character slot and click a character, then if it was not already added to the team renter the interface and click the third slot and click on your character again. If you can’t get it to work choose the mandolorian again switch him to a different character then back and do it again, beware if you add to many characters it will crash or have significant performance loss.
