Why do my items keep disappearing?!

This has happened twice now. The first time was really weird. I had reset my game by accident earlier, and after my yelling session with Resetti, I went inside to find that my golden slingshot was nowhere to be found, as well as Chief's picture. Later on, my friend Buck gave me his picture and I put it in the same spot Chief's was. This time, something happened with the date/time settings and all of the flowers died, my town was overrun with weeds, I got yelled at by Resetti, and Chief moved without mailing me a good-bye letter. I go to check on Buck's picture, and it's gone. It isn't even in my cabinet. Why is this happening? This is the second time and I don't want to lose any more pictures!
