Invisible shrine in Vorici's daily mission.

I was doing Vorici's daily quest (open chest, and keep exile alive). I lure exile away from chest and kill all mobs, but I couldn't open box, because there was invisible lightning shrine next to it. There was no that "monument" which you normally click to pick up shrine power, but shock nova was there all the time. I waited few minutes, but it didnt dissapear.
