I can suggest triple-checking for unrouted wires.  I have a small PCB
design I sent out that had *1* unrouted wire segment, between the
crystal and the pad at the MCU, so short, I couldn't easily spot it
even after several sessions of looking at it and running ERC.
Fortunately, there's a handy via _right there_, but each board from
that run needs a hand-added ECO wire (something I used to do for a
living 30+ years ago).  v2 is 100% correct!  Lesson learned.
