[Python] FPDF looks for a font at a path I have now removed

On one machine, I created and tested code using FPDF in Python, generating a PDF with custom fonts.

Then I used Git to push that code to another machine which doesn't have the fonts. I changed the path to the new font (direct to the .tty file standalone)

There is no mention of that old path (it contains 'bpickering', my other machine's username) in my code now. See image:

Note that Resources_Dir is a string passed from main():

I did a fresh install of Conda, and all the packages FPDF included, on the new machine. When I run, the only code I run is that in the image: python3 Process_Calibration.py and it doesn't import any other scripts authored by me.

However, it gives me an error suggesting it is still looking for the path on my old machine.

How can this be? Does the font file have some kind of memory as to where it was stored on the other machine?
