Sunken Temple of Qarn - Final Boss Door Glitch

[Lexxie]

Time: 13th May, around 12:25 ~12:30 AM (GMT+8)
Frequency: Only once (First time)
World name: Hades
Character name: Cadance Crystalheart
Class/Level: Dragoon/46 (Synced to 37)
Party or solo: Party (Low Level Roulette)
Area and coordinates: The Cameral Chamber (Adjudicator fight), The Sunken Temple of Qarn (Normal)

Steps:
1. Tank puts in the fruit and flame to open the secret passage and boss room. (I noticed that after the tank inputs both the flame and fruit, there was not option to tip the scales for me. Thus I was unable to interact with the scales except place and remove the 2 stone tablets.)
2. Secret passage opens but the door to the boss room remains closed.
3. Party walks into boss room but my character is unable to go through the door. (The 15 seconds for the room locked has not elapsed yet.)
4. Party kills the boss with me still outside.
5. Door still remains and I'm still unable to walk through it to enter the boss room.
6. I had to leave the dungeon via the Duty Finder window.

Screenshot attached of the door not disappearing. Although I wished I had taken a video instead.
