In the prison scene when you kill the guard on the lower left hand side of the screen I have a problem. I killed him on the walkway to the left hand upper cell. He died on the walkway and offered nothing as loot. Wasn't this guard supposed to offer 2 keys? I ask this because I found a chest above the lower middle locked exit and have no key to open it with. I tried to bash the chest open without success.
Is this a bug or did I do something wrong?
