Stone Citadel death effect

After killing Citadel boss in The Stone Citadel, grabbing my loot. I ported out to my hideout to unload to continue finishing my map. As soon as I re-entered my map, I get beamed down by lightning and get 1 shot. This is the 3rd time this has happened. Can you please FIX YOUR GODDAMN GAME... This is already ridiculous; it's been 2 months with fixes on bosses and yet this is still in the game.

Bump on this. Just got killed by it, didn't even port out but decided to walk back to pick up another item when the lightning bursts hit me.
Resurrected, ported out, came back in and assuming the lightning was definitely gone by now, it started blasting and killed me again.

Please fix, luckily I wasn't playing a hardcore character.
