I've come across this situation twice. I'll be playing silently, hiding bodies if I must and being generally sneaky. While playing, i'll make a mistake and cause the the AI to go into an alert state. So i'll reload a previous manual save and for some odd reason, the AI will immediately go into an alerted frenzy again. I swear i'm not crazy, and i'm not loading up an autosave. My most recent encounter with this was on The Royal Physician mission. I also received the Manipulator achievement without ever trying. It just randomly popped while playing and i'm not quite sure, what i'd done to cause it to activate. Weird stuff.
Anyone else encountering weird bugs?
