I found four chests on earth already, but didn't get a Sparrow yet, so which chest am I still missing? I found: 1.) the chest in the black stone cave on Forgotten Shore, 2.) the one in the rock wall on Forgotten Shore, 3.) the one downstairs in the building leading to Dock 13 on the desk, 4.)one on a building ledge up high outside the dock area (I think the ledge was outside the dock area, but it was definitely high up on a ledge outside on the first map) So what's the fifth chest I need to find to get the Sparrow please?
