Morgan spiral
If the event to give the tree life, Escort Brugh to Morgan’s Spiral, is not working/bugged then you will have to wait for a server restart as ANet say they can’t fix such things in the running game. Maybe walk back towards his spawn point to see if he’s dead and needs reviving.
umm Brugh is right next to the tree sooo. I see no option. Id rather they just make the tree stay bloom with no event. When event is up tree is hiding. Thus solve all the problem at the same time. Unless If arenet implement an option on a 24 hr cd to reset chain of event back to root but does not grant any thing other then progression of chain event to next one ?
