NPC Spawn Issue: a willowisp pathing issue in Erud's Crossing

[Burrito]

I saw of group of 3 willowwisps traversing the outer water regions of the zone today.

I tried chasing them down to kill them, but they went REALLY far out into the waters.

Here is a picture using bind sight to show how far out they go relative to the zombie ship

At one point, it seemed to share the pathing of The Sea King- but I'm not 100% sure on that.


Edit:
Added Video to show pathing and teleporting
