With three autosave posts in the last 10 minutes I am posting my replies in those threads as a post. Please read.
Hope this helps you all because too many people rely on autosaves, lose hours, days, weeks, months of work.
Use a phone timer if you always forget to do manual saves. Just set a 10-20 minute timer, and when it goes off, take the three seconds to dismiss then restart your timer.
One thing I like to do is first, do manual saves. Never rely on autosaves. Second, I always save under a slightly different name (i.e., Forest Park 1.1, Forest Park 1.2, etc) every time I do a save.
That way I have older versions if needed that I can go back to. I delete the oldest saves after every three saves.
Maybe that will help in the future.
