Shortly after respawning, the player's skin turns into a messed up Steve skin. It fixes itself a second later, though.
After dieing (it doesn't matter how) and then respawning, the skin of the player turns into a messed up Steve skin, but returns to the normal texture about a second later.
How to reproduce:
1. Go into F5 mode (not necessary but makes it easier to see the bug)
2. Kill yourself
3. Watch as the skin bug comes alive!
