pattern lines disappear after using pdf stitcher

[squikler]

I'm trying to change the line thickness to 4pt and BRIGHT GREEN, which i've done a million time without issue in PDF Stitcher, but for whatever reason, on this file, it shows it writes successfully but adobe says there's an error and doesn't show any pattern lines at all, just the titles and grid. even if all sizes are selected, i just dont get it. (I've managed to make it work as downloaded but still cannot get it to work with pdf stitcher even the newest version)

Steps to reproduce the problem

1. open girls boyfriend cardigan projector pattern,
2. deselect all layers except 6
3. chnge line color to green 4 pt thick, solid
4. apply to checked layers
5. select titles box
6. generate pdf

Thank you for the report! Sometimes processing the layers hits a command that I'm not handling properly. I think I may be encountering a similar issue with the print at home version of the free Laundry Day Tee, so I will see what's going on there and try to get a fix for the next release.

Unable to replicate, I think this was an old issue.
