i was on my world and my computer died and I plugged it in and turned the computer on, I didnt realise it wasnt plugged in at the wall so it was on emergency power and i didnt realise, it opened minecraft right where i left off and i played for 5 minutes and it died again, and i plugged it in properly and opened minecraft. I tried to open my world and but it was gone. i had two worlds and i only have one now.

Steps to Reproduce:

1. Go onto a world
2. Let your computer run out of battery
3. turn on your computer
4. run it on emergency power on your world
5. let it run out of battery again
6. reopen minecraft
7. your world is deleted

Expected performance if the bug didn't exist:

Minecraft should have kept your world but it would be not fully up to date (Because of autosave)
Screenshots/Videos:
