1 phase Olroth? Got stuck in arena

I just defeated Olroth (around 1600PST, 05/31/25) and he died without reviving. Dropped all his loot, too. But when I tried to walk out of the arena, the red mist was preventing me from going forward.

Since portals are disabled, I'm also currently stuck in the arena. Hoping it will reset after 15min and I'll login back in hideout...
