When you go to the capes page, I get to choose either the "pancake" cape or the Minecon cape, but when I try to switch between them the changes don't show on my character only when I switch tabs or exit the creator itself. Also, removing your cape (pressing on none) does not work. I tried everything but to no avail.
NOTE: This issue is with Custom uploaded skins, using the character creator itself had no issue switching between capes but both had problems when attempting to remove the cape itself.
