These 3 wires were *really* short. Nothing I did found them until I came
across a “trick” which is to zoom out so the board is tiny and then with
the route tool active, just “click” on spot on the board. In short order I
found all 3 remaining wires. Using that technique, I found the 3 remaining
wires in less than 5 minutes (vs the over an hour looking for them last
night).
Cool tip!
Have you tried the "zoom-unrouted" ULP? That should center the
display on one of the unrouted traces. From there you can turn
off the routed layers, pads, etc and zoom in more until you find it.
Repeat as needed for additional unrouted wires.
A good choice of placement and routing grids should minimize these
problems, but of course picking a proper routing grid is non-trivial
when a variety of odd (metric and imperial mixed?) spacing is involved.
