Grip of Kulemak fight Invisible boss - bug id 944326129

As the title states the boss goes invisible with no health bar, happened after the first time I killed him but reset when I was killed by the invisible boss, killed the second stage and again went invisible, I think it is to related to lightning warps culling strike destroying enemy corpses. Dying and respawning makes him visible but has no health bar making it a very tense fight

Attached is a video of the "fight"
