KiCAD v5.1.2 - Router finds ghost circles where arc where used for the border

[der.ule]

I just starting routing my first non-square board with v5.1.2 and unfortunatly there seems to be a bug related to routing.

When I start the routing, near the border with arcs, there are some “ghost” circles, that do not allow the routing to continue, if I select, "Show collision I get the following:

Routing near the border’s arcs:

Restarting KiCAD and the machine, did not help. Any ideas?

I think that this is a known bug in 5.1.2.
5.1.3 is already on the download page, in the previous releases section.
I guess that we are waiting for the Blog announcement.

5.1.3 is already on the download page, in the previous releases section.

More direct link: https://kicad-downloads.s3.cern.ch/index.html?prefix=windows/stable/

(“previous releases” sounds misleading in this context, but that’s what the page says. The download page includes all released stable releases.)

good that I did not immediatly download v5.1.3

5.1.4 coming soon (5.1.3 got skipped because of a bug)

https://lists.launchpad.net/kicad-developers/msg41795.html Wayne said: I’ll update the release announcement and there will be no official 5.1.3 release. 5.1.3 won’t be officially announced, 5.1.4 has been tagged and will be released and announced soon. There are 5.1.3 packages out there but it shouldn’t matter. This hassle was due to one bug which caused updating the footprints on a board to loose their positions. But now we got some other bugfixes, too, without waiting much longer :slight_…

[davidsrsb]

5.1.3 is not disastrous, updating footprints was broken and you should ALWAYS make a back up before doing an operation like that.

Warning msg : Cannot start routing inside a keepout area or board outline

5.1.2 has a bug with cirlce or arc edge outlines. Move those edge cuts to another layer temporarily, move them back when you are done routing. Or you can update to 5.1.3 release candidate https://kicad-downloads.s3.cern.ch/index.html?prefix=windows/testing/5.1/
