I have never had this problem before. But suddenly I have been working on the same ornaments for almost 24 hours. I couldn’t figure out why all of a sudden everything was coming out scorched and smut smearing everywhere. Finally, I found the culprit! I made some shiplap ornaments in illustrator and finally found out that every time I save as an SVG from Illustrator, it changes my lines to double lines!! I have never had this issue before and don’t understand why it is all of a sudden SUCH AN ISSUE!! I have ruined high-quality material! Several times now!! HEELLPP ME!!!
