Mortal Sins Tier 29 Bugged - Help please

I was trying to fix the gaia engines but teleported back to Agartha. Now I need to re-enter the dream but I am finding it impossible to do so.

Is there a spot in the chasm that I need to locate? Alternatively if that part of the game is bugged can a GM reset the storyline to tier 28?

Isn’t there a portal to the dream on the left hand side of the platform in Agartha that has the city portals on it? If you stand in front of the Seoul portal then it should be just behind you I think…

If you did what I think you did you will need a GM in-game.
