I'm playing on the 360. I'm sure this is a bug; if it isn't, it's a curiously unexplained event that makes little sense to me!

Upon entering the room where Curnow and Campbell are to sit their meeting, the targets enter the room and immediately run furiously towards the far door, shouting "I'll find you!". I have not altered anything in the room, including the posioned drinks, nor even had an opportunity to. There are no knocked out enemies in view, nor have I engaged in any suspicious activity within or around the room. They just launch immediately into a wild sprint. If I stand in the middle of the room, they seem to ignore me completely, far more intent on their Benny Hill-esque chase sequence. Reloading saves seems to make no difference.

I have encountered a number of people experiencing this same glitch, and so far no answer for it seems to be concrete. Can anybody shed light on this?

Seriously? Nobody else is experiencing this?
Bethesda, are you aware of this?
