I make several patterns by open jpeg file on illustrator
and drag the photo into the swatches box and 'save swatches' out of it
and then I saved all of them as 'Save Swatch Library as AI'
now I open my working file where there are line drawings and I open my previous pattern library
I apply that pattern as a fill color for my line drawings
I saved my file in 2 version as AI and also PDF(preserve illustrator editing capabilities and create acrobat layers from top-level layers) and I closed the file
but when I reopen both my AI file and PDF file, all the pattern I made in the line drawing disappeared. So my drawing is filled with nothing.
*I tried unchecking the 'preserve illustrator editing capabilities' and 'create acrobat layers from top-level layers' and it works when I reopen. But I still need file that I can come back to edit it
Can you please help me what step am I missing here? I don't want to redo it again every time I open the file.
