Ch6, Key for prisoner is not where bloodb's guide shows (this time through playing)

[Windkun]

Oddly enough, my first time playing I got towards the end of Ch6, this was on version 1.0, now with version 1.2 I am replaying the game, got to Ch6 I looked around for a good ten minutes remembering it was alot easier, I checked out this site and found BloodB's and GreyB's guide, downloaded the video and viola its right infront of the sandbags behind a box..

so I relaunch the game, go right to the location next to the cage with the human prisoner in it, No keys on the ground. (and yeah I went to the exact spot)

is the game bugged? do I need to restart the level? did it change via patches?

Please let me know, extremely confusing the area down there is not very large and I've been back and forth.
