Base Overlay Generate Bitstream Fail - PYNQ 2.5 - Vivado 2019.1

Hi guys,
I have been at this for a few days now with no luck. I have been attempting to rebuild the base overlay in vivado so that I can edit the AXI SPI1 clock divider attached to the Arduino IOP (I could not set it properly with XSpi in cell magic via python). Once I source the IP and build (all build correctly), I can easily navigate to the SPI1 and change the divider.

I save the project, generate the HDL wrapper, and then run synthesis which runs fine. Implementation, on about 4 machines now (all done with fresh pulls from the 2.5 release) give me the following error:

SOLVED: The base.xdc file was not loaded correctly.

Forgive me for all of my trivial posts. I am a novice at FPGA design + Vivado tools. I hope that others who are exploring this hardware can learn from my mistakes.
