which saves itself?

In my message folder.. I was writting a message to a friend.. it had saved the message since I allow it to at a certain amount of time.. it was a long and involved message reqarding some issues here.. and after clicking send I was booted from the site.. I finally got back in.. but, noticed it was not in my sent folder.. Nor am I able to find that message anywhere else??

What good does saving the message do.. if you can't retrieve it after getting booted.
