On Gandara server i had just done the “Destroy the dragon totem” part but the NPC died from condition damage (i think) at the exact same time it finished.
I revived the NPC as the champ shaman starting coming and and then spoke to the NPC at the exact time he said “we have to interrupt the ritual”
Now it is broke as NPC just stands there and champ shaman just stands there like in the screenshot.
I came back later and the champ shaman is gone but the event and NPC are still stuck.
I notice from other events i have broke in the past it is mostly from getting NPC’s killed at bad times. maybe make some of them invincible as its annoying having around 20% of the dynamic events in this game broken after a few days and having to wait for a patch and servers to reset.
