Guild Wars 2

The event in Brisban wildlands where you must help the priory return the energy core to the Henge of Denravi cannot be completed. Researcher Lewin Frazar is standing in the marsh with his npc escorts (who are constantly darting around him), not moving or reacting to any monsters nearby.
Researcher Elspeth Andryan is standing on top of Explorer Adelia in the middle of the priory encampment, giving the (seemingly) event-specific dialogue about wanting to take the item back as soon as possible.

I have this same problem on the Eredon Terrace server. Scholar Eleanor Taelyr is asking the character whether he wants to help and the event gets posted to the right top corner. But the same thing described above is happening.

Same thing on Tarnished Coast, the group headed into the Henge is just standing there.
