Player Skulls sometimes loose their skins.

After ~10 minutes from placing Player Skull in multiplayer, their skin sometimes replaces with default player's skin (screenshot is attached). Also, executing "/give [player] minecraft:skull 1 3

{SkullOwner:"[player]"}

" command (I used MHF_Melon's skin), gives me player skull with no skin on it, and reports an error in the server console (server log is attached too).
