Well, having had no response here, I wrote a Python program which reads in the .pcb file, checks all the lines to see who connects to who and which lines connect to pins, then verifies that at the requested nets match what the line, vias and pins actually do. There were no missing vias, so those perplexing messages apparently convey nothing important.

But, given the silence here, I suppose the real message is that I should be using pcb-rnd instead.

Cheers

Cam
