shape has NaN vertices when adding new shapes to the aggregate shape encloses a void; error assigning shape to antenna

I am creating a PCB antenna pattern adding together copper Polygons and rectangles to make the PCB trace pattern. The copper traces short back on themself forming a region with voids in it.
I have used shape.Rectangle() and shape.Polygon() to create the elements and added them together.
When I show the copper it looks right (needs a little cleanup, but OK).
When I show or mesh the antenna it throws a triangulation error.
Adding the last rectangle that closes the shape causes an NaN. This error was NOT happening in another pattern (make a shape, remove a notch from an edge, bridge the notch with a rectangle…).

…
copper = shape.Polygon(‘Vertices’, 0.001*[MinX MinY 0; MinX MaxY 0; MaxX MaxY 0; MaxX MinY 0]);
stem = shape.Rectangle ("Center", 0.001*[StemX MaxY+StemLen/2], ‘Length’, 0.001*StemWid, ‘Width’, 0.001*StemLen);
copper = copper + stem;
… add rectangles till a closed loop is formed. feed point in stem and loading reactance at far end…
…
show(copper); % looks OK other than jagged corners, see below
Ant = customAntenna (‘Shape’, copper, ‘Load’, Load);
show(Ant); % –> error. If commented, mesh(Ant, …) throws similar error (same error, different call back path)
createFeed (Ant, FeedPoint, 1);
meshconfig (Ant, ‘manual’);
mesh(Ant, ‘MaxEdgeLength’, .06,’MinEdgeLength’, 0.0005);
