Doesn’t save

I recently used google docs and google drive for a VERY important project at my school that was about 50% of my overall grade. I finished my project and was about to print it when half of it got deleted. I was mad because everything is supposed to save in the drive, but it didn’t. I spent a LONG time rewriting whole whole thing with my partner.
