Skulls often show an outdated version of the SkullOwner's skin. For example, if I take my own skull, it seems as though the game picks one of my 8 most previous skins at random to display. In a single day it is not uncommon for it to change to a head I used half a year ago, then change to my current skin, only for it to change to the skin I used temporarily for the holidays a minute later.

What I expected to happen was...:
for the skull to display my skin

What actually happened was...:
the skull chooses random skins I've used in the past to display

Steps to Reproduce:
1. get a skull, mine should give a good example (skull 1 3

)
2. place it in a world, preferably a server
3. check back on it every day or so

(ps. I have not been able to reproduce it with any other player head. I think the problem may have something to do with the fact that I've changed my skin 8 times in the past 4 months)
