In my older boards I use polygon fills around my regulators on both the top and bottom to act as a heat sink. I then use a bunch of vias to connect them thermally. It may be the new version of eagle that is causing a problem, but these vias are ending up in unrouted layer with airwires even though they have the same name as the polygons (like ground plane vias). The pour isn't working properly either.
Can someone please tell me what's happening here?
