Reminds me of a job we did with my old EC. The woodworker changed the dimensions of the custom cabinets without informing the GC (I forget if the customer changed them or if this was simply a goof).
We had installed a box for the over sink sconce for "X" centerline, and while the cabinets were being placed discovered that "X" was now +/- 7" out of line.
Yes, we can change the box location.
No, it was installed according to the original prints.
Yes, this does constitute a "change".... sign here please.
