No matter what you do they will fly back to the old place. The difference, when forcing them to reorient, is that they get back to the old place, can't find the hive and then think... "oh yea, I remember that branch now..." and head back to the new place. They will continue to go back to the old place for a couple of days out of habit every time. Without the branch they will circle in wider and wider circles until they find an hive and move in.
