Trail of Chaos Impending Doom Bugged

I have been running Trials of Chaos this past week and I have noticed an issue with Impending Doom. Occasionally when I'm doing a trial like collecting soul cores and running around the map I will walk away from an area where the circle is spreading and I will hang out for a second until a new circle spawns where I am. Then I will walk back to where the first circle was and there won't be any indication on the ground that there is a circle currently there, but the explosion animation will still happen and I will get hit for massive damage with no way for me to know that was about to happen. It seems like only happens when I'm far enough away from the first circle that it is no longer on my screen.
