Hi Branko,

The small island clearing feature does not work.

I would suggest NOT using "full" polygons, if you have enabled that, as you
will find that PCB also cannot track connectivity correctly if the polygon
is cut into pieces. Instead, use the default option of non "full" polygons,
and let PCB keep only the largest polygon piece.

You may need to add multiple polygons to cover the areas you want.

Peter
