Act 3 The Molten Vault boss bugged.

Boss started walking towards lava to begin his wave phase, at the same time his stun buildup was almost finished so i threw Sunder at him from a far and staggerd him before he started the phase.

He then started walking slowly towards me like he would be in the lava wave phase but wasn't throwing any lava wave, he just stuck in slowly walking mod getting out from the lava in the process and never stopped until i killed him easily, cause he wasn't attacking me at all, just walking.

Additionaly while he was walking and i stunned him he first started having palpitations then getting back to slow walk mode again so the stun didn't fixed his bugged state.
