Closing world during ender dragon respawn and reopening it causes crash

    • Confirmed

      The bug

      Closing a world during the ender dragon respawn sequence and reopening it causes a crash. This could be caused by the new advancement "The End... Again..." (end/respawn_dragon.json) in case it tries to track which player placed the end crystals.

      Warning: Only try to reproduce this in a seperate test world since the world will be unusable afterwards.
