I'm playing the High Overseer Campbell mission. I've made it to the meeting room without being detected, but every time I enter the room, without exception, Campbell and guy I'm trying to save instantly cut off their conversation, Campbell shouts "I'll find you!", and then both of them run out of the room.
I've reloaded several times from different save locations. This seems to happen no matter what I do. Is this intended behavior? (I can't imagine it is).
What can I do to prevent High Overseer Campbell from running out of the meeting room immediately after I enter it? Is this a bug?
