I am playing the Overseer Campbell assasination mission and and every time I try enter the meeting room , Campbell, and the guards stop their conversation, the door just opens by its self, they run out saying. "I'll find you". Every time they will head out the door on the right. They don't even bother to fight me. Campbell runs to his secret room and the other important guy runs outside. The guards just stand there clueless. This will happen no matter how I enter the room I don't even have to touch the drinks.

I have tried going through the hole above the door, and the window, and no matter what, they interrupt their conversation and run out. I tried reloading and even restarting, nothing works. I looked this bug up and it seems that A LOT of people are having this same issue. Please help.

I'm having the same issue, and this goes as far as the other versions of the game too. The forum Mods have only commented briefly on this. I can only hope that this is listed in a future update, as I've received no confirmation or information.
