When I modify a photoshop image and illustrator automatically updates the link you can close the file without saving so it recognized the image link modification but did not require a save when closed. at this point file date and time do not update to current image replacement. this poses a serious problem in the commercial print industry. Archiving files is based on modification dates and times. If you don't update time and date on file with new image placed it has not
been modified for archive. This is something that has changed in the recent cloud series updates. It was working fine since 2000 and now its not working properly. You need to stop relying design needs and pay attention to the industry as well.
