That sounds like a chest in Guardian Takedown.
Could be possible to add another chest to Sanctuary? or, Maybe it had to do with this theory:
Or an alternative use for VIP points that didn’t work out?
My first thought was the door under the bridge, which feels like it should be something, but never gets mentioned. And diamond room would fit with the diamond keys/chest, so that would be a good place to put it.
Given the whole “missing raid boss” in Ascension Bluff, behind the doors you can’t open, perhaps there was a bunch of cut content, for time reasons, which included the diamond room.
In all reality of the situation, it could technically be a room that Butt Stallion got dismembered,…
It’s next to The Champagne Room. Also, no sex in the Diamond Room, either.
