Invisible Dark Rift Ruins Guard Tower

Bug Name:

Invisible Dark Rift Ruins Guard Tower​

Bug Description:

I know this title is suck.
but, it's a bit complicated.
It's better to explain it with a video.
Why there are two videos, I thought the relog worked, but it didn't, so I recorded the second video.


This coordinate is the spawn point of the Dark Rift Ruins Guard Tower.
and uh... i killed it, but i kept reducing hp in this area until death.
Kill my target is Ruins Guard Tower.
I have relog, when I don't move, I don't lose hp, but when I start moving, there's an invisible Ruins Guard Tower that wants to kill me.​

How to reproduce/proof:
