Guild Wars 2

There are a couple events that I played during the Beta weekends and that are listed on the wiki that I haven’t seen occurring since the game’s release. The events I’m wondering about are in Giant’s Passage of Kessex Hills. One event is “Use explosives stolen by ettins to collapse their caves” and the other is “Defeat the brutish ettin chieftain.” What happened to these events? Were they removed from the game, or are they still available? If they’re still available, how do they get started please? Thank you.

Ok, I changed servers and got these events. They were bugged on Dragonbrand.

I’ve been camping this area for 1-2 hours at a time since I posted this question and STILL haven’t seen these events start. Please! ANYBODY have any information about these events?
