PCB pcb.footprint.reference_mathces().move(x,y) not moving dependent items

[dwillmore]

This very well may be user error as I am not a python programmer, but I watched the video a couple of times and read the readme.md as well. I'm trying to move a bunch of diodes in my PCB to a staggered grid. I've used a spreadsheet to develop the formula for their locations and it agrees with the x and y values that I get from my python code if I just use a print() instead of the .move().

Here's the code:

 for column in range(0,10):
     for row in range(0,10):
         diode = (row + 10 * column)
         y = 4 * row + ((column % 2)*2)
         x = 3.4641 * column
         pcb.footprint.reference_matches('D.?')[diode].move(x,y)

When I load the pcb up in kicad 7.0, I get:

It looks like the silk for the LEDs is close to right (but still wrong). But the holes, references, etc. are up in a crazy jumble negative of the origin. Any guidance? I used .move() because it's supposed to take care of the things that depend on the object being moved so that they stay together, but that doesn't quite look like it's working. Or I'm holding it wrong, which is a definite possibility.
