One thing to beware of though… is when you “Save as”, it’s saving the dimensions of the file different… so I’m seeing some resizing problems which I don’t get when I use export.
I’ve just started experiencing this same problem.
.AI files that used to export without a problem are now showing up as blank SVGs if they contain raster images.
Well, I talked to Adobe yesterday. Basically we reset Illustrator back to defaults and now everything seems to work fine. Did have to rebuilt my settings for use with Glowforge but it works now.
