Did "Ticket to the Major League", found the cyberpsycho, knocked him out with a system reset and got a police warrent (one star). Ok, that's not the bug (although it is one) but then I've tried to kill the police which "teleported in". None of my cyber abilities worked on them. I'm running a full netrunner build and usually killing lots of enemies is no problem scanning the police did not trigger any cyber options; just the scan result of the NPC.

I thought it might be a line-of-sight issue...

Police invulerable to cyber skills
