Hello! I'm trying to report a bug that might have been intentional... or just unknown as not too many people would be stupid to try. (I'm just a curious Mi'qote)

Date & Time: November 15, 2018
Frequency: 1
World name: Jenova
Character name: Tsubasa Ibuki, Hikimus Prime
Retainer name: n/a
NPC name: n/a
Monster name: n/a
Class/Level: n/a
Party or solo: Party
In-game time: (don't remember this one)
Area and coordinates: Yanxia, (17.4, 20.2)
Steps:
Note - This bug didn't really do anything to me, as I had the area unlocked already.
1. Hikimus Prime is doing main storyline quest, and haven't done the initial quest line in Yanxia. She had to go to The House of the Fierce, and out of curiosity, I tried going through the barrier that blocks off the two area (at the moon gate) via ceremonial chocobo, with Hikimus on my back seat. We got through it, simply by flying into it.
2. Hikimus could see the supposedly broken aetheryte at her stage of the story as perfectly normal one, and could attune to it.
3. She can freely teleport in there now.

I think it might have broken the game for her if it wasn't her second run, so I was just wondering if that was intentional or not known.

Thank you!
