Actually the offset edge on this file fails. I made a copy in case you want it. Most of the range it simply refuses, but at a certain range it looks like this while trying to offset. On the top middle something is clearly going wrong (that curve that should not be there). I am trying to get a -2mm offset.
Edit: on the Shapr msix install, can I trigger a manual update or does it have to be reinstalled for new versions? My project files are still not easily accessible this way, I presume?
