ok, mods, if this is not permitted, let me know. I have a question that is kinda on the gray side. I was working on my novel, uploaded it yesterday, got my word count, saved what I was writing. I thought. Now, today I went to work on it, three pages are now missing, the last three pages. any idea on how to get it back? I don't care about the word count, but I had some really go scenes and now I can't remember what I wrote.So, my question is, how do I get the pages back?
