Well I'm not sure what you guy's have been up to... Maybe, it needs a particular order of operation...? Not sure, BUT, if this was me, looks like it works just fine. I've included a few files. Maybe you guys can see whatever you are doing wrong.
Might have something to do with saved files. Because my first test was laughable. Not sure there is a bug, or what exactly that is all about. But something fishy does exist. I think within a file labeled untitled.
then another test...
Then I changed my approach... and saved the file and did what I normally do, test one
So that worked... So I decided to fudged a bit more. If I was using this PCB to ground to a chassis, this is exactly how I would run it. Place VIA's exactly as you would want them. Then all 4 resized to small .4mm holes, then bottom only copper ground fill. After fill, resizing VIA's to 4mm/.9mm ring. Beauty
