I'm in my second game and I have a Ghost run going. I've just started The Golden Cat mission and assassins have started to attack me. That never happened in my first low-chaos game but I was detected and some guards died from some security systems.

Two questions: Does a Ghost run trigger these assassins? I have no other ideas since I have not killed anyone, but a guard died, probably from rats. I'm using sleep darts on the assassins...any other tips for dealing with them non-lethally? Thanks!

There is a group of 3 assassins that I can recall during that mission, right outside the distillery district. Near the alley with Grif, they're a bit further up in the apartments there.
