horrendous issues with file corrupting.
I lose work now on a daily basis.
Thankfully, If I save my .AI format with PDF compatibility.
I'm able to open the corrupt files on an old version i've got installed on a very old Mac Mini.
Without that workaround, I'd have lost countless jobs.
Looking into alternatives to using Adobe Illustrator, surprising how terrible its got.
(I love Adobe too, but getting so stressful now, not knowing which files will be OK, and which will corrupt)
