Going to avoid spoilers as best I can.
I’m past a certain happening here but I can’t for the life of me understand how to get to the other side. I included a picture because I’m terrible at describing things.
Send the elevator car closest to that side down then back up so you can drop on top of it. Then while on top scramble up the scafolding in the north eastern corner. This should get you on top of the structure. Then go to the south eastern corner and slowly walk off. You should be floating in mid air. Then dash (-25% equip load) straight to the right. You should land on more invisible “something” that lets you get over to that side. Decent amount of Spruce and Iron Ore for farming over there.
