When you die you lose his normal skin, even if I go to the Nether.

Here is a little video to watch it. https://www.youtube.com/watch?v=k-sNjOaeaVY&feature=youtu.be

When I die I lose my skin this is so when I go to the Nether. I have tried it on a server because I lose my skin for me for other players, it will display normally.

*It may also be that you lose your skin when you go to the end, I tested it is not.

See the video that has not yet been repaired and 14w20b I have also tried still the same error!
