Mob Head Dupe Glitch

[AlohaLegend]

Hello there, I am writing in about a Dupe glitch I recently discovered involving mob heads. When a Mobhunt generated head is put on a players head using essentials /hat the player can then log out and log back in and the head will get duped. If you repeat this process with a command given head the head will not be duped. Thank you for looking into this.
