I noticed in the asuran fractal that the harpies now become invulnerable when they are attacked from altitudes above or below them. However, the harpies are able to attack us from any altitude. I can see this functionality being correct for melee mobs but for ranged mobs to become invulnerable is just not correct. Please fix. If mobs can attack us we must be able to attack them. And of course vice a versa.
