Forum:2nd Developers Chest

Recently I sold my Xbox 360 for a PS3 (bad idea, I know) and I got the borderlands GOTY, and the borderlands GOTY strategy guide. Looking through it I found a part about the developers chest, and it said there was a 2nd one in the eridian promonotory. I checked here, and it says nothing in the section. Well, I am only 25 at the moment, so I can't check, so I was hoping anyone who had the guide and could go there could check if it really was a developers chest. Apparently, its somewhere at the edge near the vault entrance.
