LibreOffice odt document disappeared

Hi,

I was writing in a document that I have for a long time ago, and suddenly after I closed and saved it, it disappeared from the hard disk :( How is that even possible? In the "Recent documents" section in LibreOffice it still shows up, but when I click on it to open it says it doesn't exist any longer :( I'm totally disappointed by this and I don't know if it's reversible...what I know is that I lost precious info that will never go back...


If you have any ideas, care to share...
