Skulls have really weird bugs, I don’t know if it is possible to fix it, but sometimes a single skull of mine will rotate through the 3 different skins I have had in the past.
I had this before too. It’s because of the new way it is handled to change as the player changes skins. I would place it on a block before you store it somewhere Bottom line, if the name is on there twice (for example: Jdawger’s skull Skull of Jdawger), it’s no good. If it has one name (Jdawger’s Skull for example), then the it should be fine
