Funny story, I found it after double-checking the area... My apologies for... wasting your time, good sir. Uh, but please consider the idea I forementioned, regarding the list of locations and what's inside of them. I heavily believe it would be extremely beneficial for future issues like just now. Lol

Try to download the full game. You can copy&paste the entire content of the www/save folder from the old to the new game folder to keep your progress.
