Does this occur when upgrading from 1.17 to the latest prerelease?

Hello, would it be possible for you to attach a backup of the world from before opening it in a 1.18 version?

Indeed, the provided world doesn't upgrade properly to 1.18. But this seems to have been fixed at some point, as the world upgrades correctly to 1.20.2.
