Stone Citadel Doryani bug

I was in Stone Citadel and i killed Doryani, as i was looking in my inventory some thing suddenly spawned and attacked me with a flurry of lightning bolts, stunlocked and killed me.
Doryani was dead, i had wiped every enemy out.
What the fuck?

Same here.
Guys, that was BS. I was working so hard towards my path to this citadel. And now I'm killed for no reason. WTF!? I have not even picked up the fragment =(
I'm frustrated to the point of quitting the game!

And that's important. Doryani was dead for good 20 seconds when it happened. I had a full hp. There was no enemies in the boss area, and there was no visual effects about was is going to happen. And there was another bug, I tried to throw the item on the ground from my inventory at this very moment, and for some reason I couldn't. And then lighting struck. Next thing I know I'm in my hideout with this stupid helmet.

You cannot imagine how upset I am. I don't have time to play all day. And my atlas was ridiculous, there was no direct path to the citadel, when I first found it. I was forced to wend around 30+ maps. With my pace of the game it effectively wiped out the two weeks of progress.

Even this message I was barely able to sent, got: "Request blocked. CSRF validation failed." many times. So I switched to Chrome incognito to do it.
