Character Death Due to Boss Mechanic Bug - Doryani's Machinarium

I am writing to report a potential bug that resulted in the death of my Hardcore character. I was fighting the boss in Doryani's Machinarium. After he transformed into his robot form and activated his "claw" skill, I successfully defeated him.

The boss died and dropped the loot, but the mechanic stayed active. I was identifying the items in my inventory—more than 5 seconds after the boss had died—when the leftover mechanic killed my character. It doesn't seem right for a boss mechanic to persist and remain lethal so long after the encounter has ended.
