I was playing on a world with full Netherite Armour Prot 4, Unbreaking 3, thorns 1 on a normal survival world and then I shut down my PC so i could take a short break. When i opened minecraft (Vanilla) again, and clicked "singleplayer", my world did not show. I then checked the "saves" folder and saw my world. I then came to the conclusion that my world has been corruped for the 3rd time. This has happened to me before and i assume it is because of exiting the world "badly" (as in shutting my PC down without saving).

I would suggest you to make a "backup every 1 - 5 mins" option, so every [selected mins] the backup folder will replace again and again. This would definitely save alot of worlds and player data.

Pls fixx ittt
