So on my second playthrough this time, killing all hostiles.. After rescuing Emily from the brothel I take her to the vip door and of she go's. I go through and one second later the game ends saying alliance dissolved! Now I've tried both ways, killing the pendletons and not killing the pendletons and still get the same result.. Is there something I missed or somebody I shouldn't have killed en-route?

Any ideas/suggestions anyone?
