I'm doing the Path of Subterfuge. and i'm on the "Ambush" quest. I cant figure out whatis wrong! Falcar comes out. he runs back in. no quest update. thus the door is still locked. i'm pretty sure its this mod causing the problem though

Did you already compare the quest stages/activators/dialog/topic form the .esp with the ones inside the oblivion.esm or other mod with the construction set?
