A couple of days ago, my laptop ran out of battery power while closed, and LibreOffice Writer (with a copy of a document I was working on) was open when the laptop shut itself off. When I turned it back on, LibreOffice wanted to auto-recover the document, so I allowed it to do so. When it was done, I noticed that the last page or so of work that I had done was gone, even though I had saved it–several times–while writing.
Now, I’ve noticed that LibreOffice simply won’t save changes to this document. No matter what I type, if I save it, close the document, and reopen it, it reverts to how it was when it was auto-recovered.
I tried copying all of the information to a brand new document, and saving it there, and it saved. Then I tried to edit it, save it, and close again, and THAT wouldn’t save. For some reason, I can’t add to or change this text, no matter what file it’s in, even if I make a brand new file for it. How can this be? Is there any way to fix this, or will I need to retype the entire thing from scratch?
