It that was Esh not spawning, leaving both bosses invulnerable.

Reference ID: 3 1888 017 751

The fight with Esh and Tul ground to a standstill when Esh went invulnerable, still using her attacks and me being able to leech off her, with Tul not spawning in to continue the fight.

I've tried dying twice to reset or progress the fight and nothing would change, Esh stays invincible and Tul doesn't spawn.

same here

literally just had that same bug

Still occurring pretty sure its been this way since release. Guess devs are too focused on poe 2 ;/
