D1 Campbell automatically detects me
Idk why, but whenever I enter the room where I could poison Campbell/his meeting chamber (doesn't matter which entrance, window etc.) his dialogue cuts off and he starts saying some generic "I see you" phrase and books it to his secret chamber. The other guards also run until they're outside infront of the whole building (in the yard). They also seem to not really detect me while they're running. Even if I sprint behind them, they don't hear it/don't react.
I guess one of my bodies probably glitched through a wall and they can detect that. Is there any way you'd know/guess how to fix this? I really don't want to replay the whole mission in hopes that this time there won't be any gliches
EDIT: I'm now pretty sure that a guard I knocked unconscious and threw into a corner clipped through it, since his sword is still there but I can't find him. That corner is also directly next to the room/spot where Campbell detects something. I just decided to use a mine to only kill Cambert and since the others have this weird glitch where they run outside, I could easily loot and Curnow survived.
EDIT 2: The game even says that I wasn't detected once. I only got 1 hostile killed, which should be from Campbell.
