Ziggurat Catarina skips stage and becomes invulnerable when delirious

As the title says, Catarina on Ziggurat T17 map skip one of her stages and becomes invulnerable in the end. I suggest it has something with infinite VLS mechanics, because on previous builds i have never seen this. This is repetable and happens in every deli Ziggurat map. Tried portal out of the map, tried dying to her, tried spawning less vaal lightning strike entities.
