[Stuck under the arena in the Kela de Thaym fight]

I just got a bug where I got stuck under the arena where the fight against Kela de Thaym takes place. I stood on the platform as it rose after the first puzzle and after the cutscene, I ended up being stuck into the platform itself, unable to move. I typed /unstuck and it put me on the floor below the arena, where I was before the cutscene. I was not able to go back up to join the fight since the platform was already up, and I was also unable to get to extraction.
