Okay, so I am writing this in Nerd Rage!!
I have done TWO non-lethal no-detection runthroughs

TWO!!!!

I have not killed a single person! I have never been detected!!! My stats say both boxes are checked for EVERY mission!

Clean hands and Ghost HAVE NOT popped up!!!

Before anybody says the words "Granny Rags" or "Slackjaw"... I did NOT even go to them on Mission 7. I obtained the sewer key some other way (must have picked it up somewhere). So I know it has NOTHING to do with them.

To me, these two are glitched!

This has really annoyed me, as the game has been out a while, and you have failed to patch this. Due to this, I will not be playing the game again, nor getting the DLC.
Shame on you!
