after finding out how to change the icons for worlds, I exited the game in second person with my armor. I came back as a marshmallow, I then found out it was my armor that was bugged. don't worry about the missing texture in one of the pictures, I took of my helmet, it is part of my skin. I don't know if it affects other versions. I saw a similar bug on here, with white horse armor on a skeleton horse. MC-93537

After a couple hours my armor fixed and it's back to normal.
