We have had a rash of buildings that are not square with the world. We have to change our UCS to match. See attached image, when we do this for a duct riser the designline will not allow the duct to follow the UCS if it goes to the next floor. If the duct just turns it will follow the UCS just fine. I believe this is a glitch. We have been having to manually fix all the duct in the shafts and do work arounds to make it function correctly.
