Before updating to this version you have to remove all plugin files (config.yml and messages.yml) generated on previous version - otherwise plugin won't work.
Changes:
- You no longer need ProtocolLib to run this plugin
- Added support for all versions from 1.12 to 1.17
- Added an option to add own blocks (you can do it in config.yml).
- Added new commands: /of reload, /of removeore, /of listores
- Recoded the entire plugin, added some optimization.
- Fixed many bugs.
And much more!
