I'm having a problem during the flooded district mission. I'm playing the game trying to get the Shadow achievement, but killing everyone, so I do not care about clean hands. So far i have the "ghost" box checked in every mission besides flooded district. I have looked around in every possible forums and tried every possible way to finish this mission, to no avail. I figured out some stuff during those runs:
1. Once you retrieve your gear, if you go through the door with the dead overseers near it, it will trigger a detection somehow. It will even show some red lightnings going off in one side of the screen, though there's no one in the room. The way to avoid this is do not go through this door, take the other way around, or you can get through the door on the way to your gear, it won't trigger an alert on the way back if you do this.
2. (I think this is the part i'm getting "detected") Once you kill/spare/whatever Daud, and get through his tunnel, after the loading screen, the music that is playing is the battle music. This doesn't make any sense, there's no hostiles, no one who can spot you or anything, and I've seen this happening only on High Chaos playthroughs. I've tried doing only this mission on low chaos (I even got clean hands when i tried), but the music plays anyways, maybe because my whole game has been high chaos so far. I don't know if this is a bug or something, but it's the only "explanation" i have.
I've tried every possible way with Granny and Slackjaw also, in case you are wondering if she's detecting me. I've killed him, I've stole her key and ran, I've even killed her without being seen, and nothing. My sewers area is filled with weepers, but it's no trouble getting through them either.
Anyone else noticed the battle music thing? If you check some youtube videos of High Chaos runs, you'll see what i'm talking about.
Thanks guys, hope you can help me!
