Immortal Necromancer - Simulacrum Self Sacrifice

Simulacrum with the rune Self Sacrifice is triggering an unlimited amount of times as health drops to 0. The Simulacrum disappears and the skill remains active.
I believe the correlation lies within the Haunted Vision amulet and the Self Sacrifice rune.
I have been unable to pin point what triggers it. Simply using the Simulacrum skill is enough to sometimes bug and sometimes work as intended.
It works in ALL content, and if you start a GR and it bugs, you will have it indefinitely as long as you do not recast the Simulacrum skill, or enter a new GR.
