Up to 1.16 orbs triggered event EntityTargetLivingEntityEvent.

This seems to be buggy in 1.17 now...

simple testcode:

   @EventHandler
   public void onOrbMove(EntityTargetLivingEntityEvent event){
	   Entity orb = event.getEntity();
	   plugin.logger.warning("EntityTargetLivingEntityEvent:"+orb);
   }  

There is not always output of orbs on 1.17.x servers!

Until 1.16 it worked well.

Maybe this affects more entities, not testet yet...
