Bug - Cannot Complete Map Due to Permanant Unpassable Wall

RUSTBOWL map was JUICED before entering. I get into the map, clear the first half, and get a big wall that I cannot pass with a Breach and Rare monsters on the other side. I walked the perimeter of the explored map, to find no entry way into the other side of the map.

I understand there are mobility skills that classes have that can bypass, or jump over said wall. However, I do not possess those skills.

I have uploaded a Steam clip of the map, and how it's not passable.
