This.. was stressful..
You may have also noticed I did this on v1.3.8, this was solely because 1.3.9 can be a bit laggy for me (especially once I get to Entrance Zone), and I also have had a few MAVs (despite having used the 4GB patch) .. So I needed a reliable version to prevent any technical issues.
