King in the Mist Pinnacle Boss Softlocked

There is an uncommon glitch occurrence when during the first phase of the boss fight, the boss teleports to one of the three elevated totem platforms, and gets stuck there. This trivializes the first phase. However, during the second phase, he stays there, while immune to damage, softlocking me out of the fight. I tried switching characters and logging in and out, yet he stays stuck.
