Hi there, my players and I are weirldy crashing when we are entering a dungeon of the mod When Dungeons Arise. Analysing the crash report, it seems to have a problem rendering the player heads of the mobs of those dungeons.

Here's the crash report: https://mclo.gs/d5LqqgU

It didnt crash before we update the mod recently, so I dont know if its a new version bug or something.
