Pages not saving when original file is archived

Hey everyone. I had a few really important documents that were open in pages for so long that I just kinda forgot where they were saved. I actually archived and deleted the folder they were in. Not knowing this, I closed the documents. Pages never even prompted me that they weren't saved or anything. They just closed. Of course I checked the archive and they weren't updated.

Is there anything I can do to get them back or am I just screwed? Thank you everyone

NOTE: It's not just with archiving. You can have a document open in pages and delete the file and still be working on it for months but, when you close it, it will be gone forever without a prompt from pages. Try it out yourself.

 

saimsaladimbamba- I have version 10.7.3 of OS X and version 4.1 of Pages. I enabled auto backups so every folder that contains a pages document also contains a backup of that document.

GGJstudios- Sorry if I wasn't clear enough about it but I did modify the file. If I hadn't, this wouldn't be a problem. This is a flaw in pages- try it yourself (if you have Lion). Create a document and save it then archive it and delete the original. Type a new sentence into the document then close it. See if it prompts you.
