So, I was running through Ungoro Crater & noticed something odd. The (elite) Spiked Stegadon's were set to aggressive. I noticed this when I ran through one thinking it was non aggressive (as the are on retail) & noticed it was chasing me down with a vengeance. I managed to get away, but just barely. Be wary of these animals adventurers & steer clear. Good adventuring to you.
