Just now I started up my server, but the world I'm in turns out to be the one that got saved at like 1am (about 20hrs ago). When I downloaded the world to find out which version of the world is this, it was actually a version even earlier than the 1am version. I tried loading the automatic backup from 4:26pm (5hrs ago) but the world was still the same as the world from 1am. I don't actually know if something went wrong this afternoon as I only turned on the server for a minute or so, then turned it off.
My username is Guccigang90000, my server ip is crinccc.aternos.me
Thank you
