Hey guys, found this little skip. I explain how it works in the video. In Port of Adia, it only seems to work on this specific door that has two switches. Unsure what implications this might have on other levels. Have a nice day!

¤Update¤ This glitch will work when the save/load is done ¤at any point in the area¤. Area meaning any loaded area between the last portal and the next portal. It's been determined that performing the glitch at the beginning of this area (immediately after the portal) is the fastest method because it also allows you to clip through walls in the underground areas as well. It's important to remember that this glitch will reset as soon as you enter the portal to the next area of the map.
