Guild Wars 2

Map: Brisban Wildlands
Area: Brilitine Swath
Location: Mountain ledge overlooking the south west corner of Enrav Exploration Post. (north of the Ulta Metamagicals Equipment Repairs icon)

Here is a group of 4 skritt, one with a service or assistance event indicator above his head.

When trying to talk to him, the whole group just runs down the hill to the north. At the bottom of the hill they form up again but with no event indicator.

Talking to the original event npc skritt makes the whole group disappear and respawn at the top of the hill in the original location. They proceed to immediately run down the hill again and form up at the bottom. Scenario can be repeated again and again.

If event npc skritt dies he will respawn at the original location with event indicator.

A lone skritt npc also spawns on the original location while the group in question is otherwise engaged at the bottom of the hill.
