I made a custom footprint for a coil (see below if the upload is not working, foo.kicad_mod (6.8 KB) ) and I needed to also create a mirrored copy.
When I mirror inside the footprint editor, by selecting all the components and doing a mirror by right clicking in the exact center of the axis and selecting mirror, what I see is exactly the mirror copy.
Then I save it and open it again and the custom pad shapes are all in the wrong place and not aligned anymore.
I am trying to figure out what is going wrong, but I am having a hard time on that.
For reference I post one of the offending custom pads in the following.
The original:

))
From those two I can see that the anchor is flipped around the zero (as I mirrored in the center of the axes) but there should be something wrong with the gr_line coordinates.
Am I doing something wrong or is this a known bug?
Thanks, Alex
