If you start up the Minecraft server and use the /give command to get a player head, it will only ever have the skin you had applied when you first joined the server. Restarting the server will refresh the skin to your latest/current one.

Steps to Reproduce:

1. Join a server
2. Use the following command:

   /give @p minecraft:player_head[minecraft:profile=*[YOUR_USERNAME]*]
   

3. Change your skin
4. Rejoin the server
   → Your player skin is different.
5. Repeat step 2

Expected:

The player head would be of your current skin, and not an outdated one.

Observed:

The texture of the head will be of an outdated skin.
