When selecting objects with the seam allowance tool, the preview (the red line) is sometimes not up to date for a while. The problem seem to occur mostly when selecting curves or curved paths.
Also it happens sometimes that when selecting a curve, it's not taking into account at all and instead I get a straight line (even though the curve is selected clockwise).
Theses problems also seem to occur a bit randomly, sometimes it works and sometimes it doesn't.
Attached are 2 small videos so that you can see what I'm talking about and also a simple val file to make the tests.
