Mistward Helm Casing from King of the Jungle Meta Event

[Dzus.8462]

I was wondering if this event for the Mistward Helm Casing is bugged. I have done this 3 times already and no helm casing. I have read the Gw2 wiki and forum posts about all 4 needs to be killed and you get it from a chest by the Ley-Line Confluence WP however I have not see a Gerent's chest at all near the WP. It never drops and never seen it drop from the 3 times I have done the event. is it bugged or is it something I am missing or doing wrong? Because I can't see how you can kill each gerent in the meta to get credit for all 4 when they get vaporized. Please help with this as i am extremely frustrated with this achievement.

I see the Gerent's Chest (it's a statue on top of a pedestal) every time I do that event. (I can't do anything with the Chest because I have autoloot.)  You don't have to kill each Gerent yourself; they just all have to be defeated for the Meta to succeed.

But where is the chest though, cause I have an idea what it would look like but is it behind something or on one of the Chak mound or what? Cause I stay by the waypoint just to see if I could see it and nothing.

Here's what it looks like:  https://wiki.guildwars2.com/wiki/Gerent's_Chest

It's pretty big; kinda hard to miss.
