Pretty sure the U/V curves flipped as well for some faces because when I select everything I had selected Friday the toolpath takes forever to generate (because it's generating a thousand small stepovers straight on instead of a few stepovers horizontally as shown) but I might be selecting faces I didn't have selected prior so can't confirm.
I'd upload the old file but the browser keeps refreshing before I have a chance to click the file's version number so I can export the file I saved on Friday. Maybe something to fix as well. Been broken for at least 5 years so mine as well.
