Crashing

I loved this game I played it for a whole week, I had a ton of progress in the game. Then one day while I was playing the game crashed, This had never happened before. I opened up the game and I was back in the same place I was before the crash but all of my items were gone, when I teleported back to my house I saw my chests were also empty. I really want to keep playing the game but I dont want to redo everything
