After following these steps, the glitch will occur.

-open character creator and open any character. Switch to the maker and not classic skins if not already.

-open any part that has a "None" button allowed and the current character has something of that part equipped (ex character has a hat, then select "None")

-sometimes, selecting other options than "None" will also trigger the glitch.

congrats, you've locked yourself out of changing that character and selecting that character. It will remove the item that you selected "None" with, but now you can't change anything else about the character; it just acts if it is perpetually loading. You also can't back out of the creator yourself, you have to reset the app to gain access to everything else. However, the character is now replaced by a perpetual loading symbol, and it cannot be chosen or changed as the button will not let you interact with it.

other characters can still be interacted with, though they need to use the side button in order to be changed. If one tries to edit the looping character through the side buttons, the character will instead be saved to the next unglitched character.

I have lost 3/5 characters this way and it's so easy to lose others if you're not careful.
