Visual bug: flame beam effect remained after enemy death in Atziri's Temple

Content:
I found what looks like a visual bug in Atziri's Temple.

After killing an enemy that was using a flame beam / fire line style attack, the fire effect remained visible in the area after the enemy died.

I am not sure about the exact reproduction steps, but it seemed to happen right after I killed the enemy think i was using "Lunar assult" and think the enermy was frozen/freeze.

Platform: PC
Area: Atziri's Temple

I have included a screenshot below.
