Zolin & Zelina Boss Fight Bug — Zolin Continues to Heal from Downed/Dead Zelina

Ran into a bug during the Zolin and Zelina fight.

I’ve done this fight four times now, and every time the same thing happens — I kill Zelina (the fast mage), but she just stands still or kneels after dying (she's obviously in a bugged state).

The problem is that Zolin keeps his ability to heal from her even though she’s clearly kneeling, standing, disabled, dead or bugged out.

Made the fight impossible to finish solo since he just heals forever. Every time i got him to half health, he heals full.

I "resolved" this by getting help from another higher-level player to kill him after Zelina was already down.

Definitely seems like something’s not working properly once she dies.

If not, and this is intended???
