CI build, and died with energy shield and 0/1 life?

I was doing an alter with tornado of rats, and it seemed as if I got one shot extremely fast, but on the death screen, I still had energy shield but no life... I don't run anything that would take my life from me as I attack... so I'm stumped as to how I lost the life when I still had energy shield? Any idea? Anyone else experience this?

Got the same bug twice today. 8k es with 0/1 life.

Just changed skilltree to monk meditate.

I know you said you didn't have any health cost attacks, but are you running a mana flask that has the 15% life cost modifier?
