Kabala, Constrictor Queen stayed burrowed

I am in Act 2 Cruel, and while fighting Kabala, she made her move where she creates a barricade around the arena and burrows to then deal damage.
She burrowed but never came back out. I didn't kill her and I didn't get the points. I stood there for 2 minutes to make sure, but she did not come out at all.
