Changed placed item outside of illustrator does not mark the AI Document as changed...
If I have an illustrator document open that has a linked placed item within it, and the document has just been save, and I modify and save the placed item outside of illustrator - AI prompts me that the item has changed and asks if I was to update the placed artwork. If I select YES, the artwork is updated but the AI document is not internally marked as changed - e.g. I can close the file and it will not prompt me to save.

This error in not updating and saving has caused images to be carried into the rip without the latest corrections which is a disaster to the prepress workflow. In the 20 years I have worked with illustrator this is the worst bug that could appear in the printing world. Color corrections are very important to the print industry and illustrator has been used for many years as a carrier page for images and art work that has been reliable until now. This needs to be fixed as it is basic file management and archiving files with the latest dates is impossible with the way things are now. Please fix this.
