Sometimes death monsters leave a standing ghost image of them as long you in the area. The only way to clear them is to log out and back in. In places like the void pool or gauntlet that can cause some problems if you use closes target . It will move on the ghost images event if its not a monster to kill.
When there are a lot of monsters you realy don't want to target somethign that is already death.
