Word just deleted the document I've being editing since. I saved the document but still opened in Word and I minimized the app to just check the meaning of a word in my dictionary app, on returning to the app, it just tells me can't open file, I should save the file on the device before opening it. I went to my files manager and discovered the document is no more. What kind of bug is this.? I'm damn upset, all my writeups and everything is gone, why for God sake?
