Pre-apocalypse Northlands..weird area??

Just recently cleared the entire area of everything alive (including pigs, possible spies) as a mesmer/necro 9 and a ranger 8. And Mr. Moa.

I'd send shots, but I don't know how to reduce the size enough.

A tip or two for anyone who wants to try and can't seem to pull it off, use cover against hunters and split patrols up at bridges and at the monk.

? I excepted a bonus scene of some sort after annihilating every single Charr...but there was none. I'm still suspicious of this area.

-My game chopped up for a moment toward the big bridge door...I saw it open for a sec
-What are the point of te chests that open with a flash of light, and give you no exp or gold?

The chests may move around every time you reenter the area.

The game chopped up again. At the big bridge door with an invisible wall, I saw smoke clouds above the bridge.
