Certain artwork disappearing from file
Yesterday I started working on some small logos for a friend of mine. They were very simple, just text and some small basic illustrations, and they were only two colors: black and red. When I finished working yesterday I saved the file and closed Illustrator just like I've done a thousand times. I opened the file today, and all of the red artwork is gone, but the black pieces are totally unchanged. Illustrator didn't crash, and I didn't get any notification that anything was wrong. I've been using Illustrator for years and have never had anything like this happen to me. This was the only version of this file, and I feel like there isn't going to be a way to recover what I lost, but I'm hoping someone might have some insight on how to avoid this happening again in the future.
