Additional context

This issue is likely related to Szum123321/textile_backup#123.

Textile backup appears to be saving worlds asynchronously, which might have caused this issue:
https://github.com/Szum123321/textile_backup/blob/04533f89fdd4d615f90932f86d46b698339d8f2d/src/main/java/net/szum123321/textile_backup/core/create/ExecutableBackup.java#L69

Changes have been made to prevent asynchronous access to ticket level propagator.
