I have a multi-layered PSD file, that when placed into an Illustrator doc, some elements in the PSD file disappear. When placing the file, if I choose to flatten the art, is when it happens, however, if I choose the other option to "Convert layers to objects", it does so without issues. Has anyone ever experienced anything like this? I am not a Photoshop expert by any means, so I could be missing something obvious. If anyone has any insight as to what is going on here, I would be grateful for some feedback.
