happened to me as well, and every time I try to restore the world to a backup, it creates multiple backups of the new unsaved chunk world and doesn't even restore the world back, getting the error 500. I was only able to connect to the world a few times, and tried each method of restoring the world in both 1.13 and 1.13.1 multiple times to no avail. everything just disappeared, and with no way of downloading a backup from 12 hours ago, all the backups with the actual world will soon disappear leaving everything gone forever.
