I think there's a bug that doesnt teleport you to the reward room after you successfully complete a sundial run. After the activity was over instead of being teleported to the sundial, me and one other guy just spawned again in the boss room, I tried shooting myself to see if I would respawn outside but I respawned in the second "pseudo boss room", i killed myself again and i respawned in the main boss room. I saw the other guy respawn in the sundial rewards area after he respawned but I tried 5 times and kept spawning in the boss room
