Chunk Reset while AFK Fishing

I recently built an AFK Fishfarm on my Singleplayer World. It's a basic noteblock design to keep casting. 

I then went on and started fishing, clicking right mouse button and unplugging the mouse to keep the input going. I left my computer on for about 10 hours during the night while fishing with a mending fishing rod. 

After I woke up, I saw I 'died' and needed to respawn. My bed seemed missing and when I went back to my house, the entire chunk in the middle of my house was reset. Storage, farm, house,... Only the chunk I was fishing in though, the rest around it was the same. I think it crashed around 9 hours after I left it on.

Any possibility on reverting the chunk to it's previous state?

Thanks in advance.
