Wasn't sure how to word this in the title, but here goes. In the second and third missions of The Knife of Dunwall I decided to go low chaos and not kill anyone. I only used the sleep darts, stun mine and choked out hostiles.
But, after the second mission it said I killed 3 hostiles and 2 in the third mission. But I didn't actually kill anyone.
I have a possible theory for the second mission. I did choke out 2 guards who fell into water after doing so. They fell off the side and it wasn't possible to get them.
Is it possible the game counted that as drowning? That seems absurd as I type it, but I have no other idea.
But in the third mission, I only left one person in water, but was able to pick him up later on and throw the body into a dumpster.
Is this just a glitch, and has this happened to anyone else?
