Placing head in anvil causes packet overload

[Frostified]

Placing player heads in anvils causes the player to send too many packets. The player eventually gets kicked for sending too many packets.

Once the player head is in the anvil, the head rapidly flashes between skins. This prevents the player from typing for some reason. You can easily change the packet limit in "spigot.yml", but it still prevents the player from doing simple things like typing and may cause severe lag issues.

Steps to Reproduce:

1. Set online-mode to false to make the server "cracked"
2. Start the server
3. Join the server
4. Get a cracked alt on using a cracked launcher (e.g. TLauncher or Salwyrr Launcher)
5. Kill the alt/Make the alt kill a player
6. Pick up the head
7. Place it in an anvil -- You may see the skin of the player head flash between Alex and Steve. A few seconds later, you will be kicked with a "Sent too many packets" message.

Server Software (That I'm Using): PaperMC 1.18.2

This plugin was never meant for offline mode. However, I'll look into this when I have the time.
