That's unfortunate. But at least it's easy to copy everything into a new file, which seems to straighten everything out. The only problem I've noticed so far is that somehow, there's a ton of bright red light inside the model, whereas it's supposed to be metal halide. Any thoughts?

I got a location snapshot and turned my model to fit appropriately on the site. I then went to Tools>Axes and rotated the axes of the model to be square with the building. But now, the Standard Views are still aligned to the old axes, so nothing is square-on like it should be. How do I make that right?
