Mansion in the Mists

The map with the mist effect near the mansion anomoly map is supposed to have the obelisk to click at the end is my assumption? I've done so many of those misted maps that had no obelisk thing.

I assume this is because the recent patch removed the boss area, and those interactable are supposed to be in the boss areas (I've only ever seen them in boss arenas).

I also have had maps being reset to be runnable after completion because the mist settled on such a map that I had already run, even though there are many incomplete maps nearby it could have gone on.

I've been trying to target these mansion bosses for a gem in ssf and I feel like they are basically impossible to get working now, as you need the mist to go on a map that has a boss, several times (I don't know how many maps with clickable things i have to do/click bcas I've never done it enough to get a mansion to open).
