Is there supposed to be a Humanity loss if you try to hack Bertram's computer? I hadn't done that in a few games, so I made my way into the oil tank and gave it a shot. My hacking feat was too low, so I left, and as I did, I lost Humanity.
I reloaded and tried four times. Here's what happened.
First time: Got as far as the corner by Foxy Boxes.
Second time: Lost it as I passed Bertram's gate.
Third time: Just into the parking garage.
Fourth time: Quite a bit further, I think almost to the beach? I just know it took several more moments than on my earlier tries.
I even broke in and left, then went back and hacked and left again. It's definitely the hacking that causes it.
I thought at first it was that I was low on blood, but it turned out to not make a difference (didn't make sense anyway).
