- Fixed a bunch of reported issues (and fixed modelengine support)

- Fixed signs not working
- Fixed villager guis not working.
- Note: ModelEngine is currently incompatible with this version of the plugin. If you are using it, please consider using the last version before the 1.21.5 support or wait a few days until we fix it!

- Added 1.21.5 support. (supported versions: https://docs.artillex-studios.com/supported-versions.html)
- Important: There are some major internal changes to our core api, (AxAPI) so there might be some issues. Please report any unexcepted behaviour at https://github.com/Artillex-Studios/Issues/

- Fixed that the sell event end message was using the wrong placeholders if a staff ended it manually

- The ItemSellEvent api event now returns a cloned item.

- Added 1.21.4 support
- Fixed some issues with commands on 1.21+ versions
- Improved the throughput of the packet entity system by a large margin (faster holograms)

- There was a debug message left in the previous version, if you use 1.21.2-3, update to fix the spam.

- Made the permission multipliers work even if you are OP.
