Sudden problem with embedded bitmaps
I use embedded bitmaps for additional texture in my illustration. Since recently updating to the newest version of Adobe Illustrator CC, suddenly I am encountering a lot of problems with these-- they print irregularly, and create glitches when saving to some formats, like pngs. I have never encountered problems like this before.

Please get in touch with us at any of the other support channels – https://helpx.adobe.com/support.html . Since this is not a generic issue that we can reproduce at our end, we will need someone to look into your machine to figure out what is going on here.
Warm Regards,
