NPC Spawn Issue: Piranha in the Temple of Marr...

[excalis]

When I have gone here looking for my Cleric spells, a Piranha mob ends up attacking me without me being able to kill or hit it. It follows me pretty much until I zone out.

It attacks while in the Temple itself, not sure if this is meant to be.

I am pretty sure I was not able to damage it as I tried to kill it so as to not have to zone out.

This is in North Freeport, Temple of Marr

Did a quick search to see if maybe this had already been mentioned but found nothing. Hope this helps!
