Putting this here until I get confirmation that it's intentional and not a bug...
Prestige Mission elevators don't change like normal elevators. I'm used to waiting for Arenas in the Clockworks (Used to do it all the time before KoA), but I swear that these Prestige Mission's elevators simply don't change.
If they do, they take a ton longer than normal ones. This is the elevator I was waiting at. I really don't care to solo fire devilites...they annoy me tremendously...
But I really had no choice. After waiting what felt like an hour and was probably around 25~30 minutes, the elevator never changed.
