96% Exploration of The Imperial refinery

[Implicitlee]

I cannot seem to get 100% exploration on the Imperial refinery I am stuck at 96% which is leaving me at 99% for Kashyyk, any one else had his Issue or know what I might be missing

There's two places I can think of. There's a hideout near THE ENTRANCE OF THE OIL REFINERY, just on the right side before you enter the structure, try checking there.

And one above the spinning top, the area with the toxic water and double jump chest. Check high up for a hidden climbing area and get to the secluded room.

Had the same problem. For me it was the location of the echo "Wookiee Oppression". On a high ledge between two turbines, just before the burning section and the elevator to Kyyyalstaad Falls.
