this whole cleaning up world bug seems to be related to wrong copy pasting of files
like... each world has 2 files... but people copy only 1 of them...

Sadly the automatic backups are about as useful as the ones Office makes. The command to get your world back is copy/paste in file explorer and you gotta do it in advance. :/

backups work as long as he doesn't overwritten then
but if he does overwrite... then yeah, useless
(to not overwrite simply do CTRL+ALT+DEL and kill game)
