Your mess came because you did not follow the old advice - move your hive less than three feet or more than three miles. In between those distances your bees become confused.... well you know that now. If this is a recent move, I would move your nuc back to the old position. Before you move it 15 feet, first move it more than three miles... wait for six weeks and move it back. Otherwise move it a couple of feet each week for a couple of months. I had the same problem with a swarm that moved into a trap and I moved across the yard... in just three days the swarm had established the trap location as home. I lost a couple of handfuls of bees.
