Boss Lightning Storms after he died @ Stone Citadel...

... so there are still lightning storms following me after i killed the boss and i couldnt pick up all fragments because it threeShoted me and i died without the possibility to pick up all the boss loot.
on the patch the on ground effects of all monters disappear now after they die, ... this one seems not right also

Almost exactly the same thing happend to me after killing the stone citadel boss. Only difference here is that I got to pick up some of the loot including the fragments before the lightning struck.

What happend to me was that I got to pick the fragments and right as I was about to summon the portal to portal out to hideout lightning struck out of nowhere and got me killed.

On the node it says Map failed. Though the quest is gone from the sidebar now. And the only thing left is The Pinnacle Of Flame quest.

It must be bugged. I have had similar problems with the iron citadel too. Done it two times. Boss killed both times and no deaths from my side, though the map node both times said failed (though both times I got the fragments there too). Buggy, buggy, buggy.
