it deleted either. I wonder if it plain can't find them on disk anymore,
or if there is some other problem with the design not matching the PCB
board.

The output might suggest that the netlist / parts list produced by your
gsch2pcb.project isn't actually matching your board. Do you have
multiple schematics or hierarchy in the project?

Check the resulting netlist, are all components appearing to show up, or
are some missing?

Do you get any errors in a gnetlist.log?
