Game Over 'bug' in Dishonored - the Pendletons

So after Doom 3 I've been playing Dishonored, definitely a Thief vibe to it, but still not as good. Anyway I was on the second main mission to kill two brothers and was offered a non-lethal method to do so - acquire a safe combination for Slackjaw the Gang Chief and he'll take care of them quietly.

One combination retrieved and I hand it over to him; up pops the 'targets eliminated' info and I head back to my pickup point. I get halfway across the yard when it jumps to a game over screen informing me that apparently I have "made an enemy of the one person who can eliminate the Pendletons" and offering to load up the last save.

This is bad for two reasons - firstly how have I made an enemy here? Secondly the game autosaves when I enter a new district  and then when I've 'completed' the quest which means I don't have a save that will take me back to the location where I can kill them myself.

Roaming around after my quest 'completed' autosave some of his gang attacked were attacked by members of his own gang who had the plague; what's that got to do with me? Turns out you make that enemy if one of the gang gets killed and when the two groups attacked each other I got the blame for the outcome.

This is seriously bad as after I first acquired the non-lethal option the gate where the plague victims are being kept opens by itself so someone is likely to get killed while you're present. So in theory it's possible to get a game open when I first returned to the district with the combination before even reaching the leader.


Through total skill (okay with some major luck) I managed to circumvent this bug. Using the Blink ability I can travel long distances. Blinking multiple times back to the district entrance I exited before anyone died. As this freezes and resets the district no-one got killed so no game over.
