Support for Minecraft 1.21.5 (This is especially important for command rewards)
Backups will now be made when the plugin upgrades to a new version (when any machine file is detected to be on an older version). The backup is called "MACHINES_BACKUP-UPGRADE-TO-XX", replace XX to the current plugin internal version, 6.8.5 being 87
Bug Fix :
Added a new error message when corrupt machine files are being edited instead of throwing an exception
