Hey all,

This update fixes a lot of issues with the leave item, this is the changelog:
- The leave item was given after leaving an arena, this is fixed now and it is given when the player joined an arena.
- The leave item did nothing on a right click, this is fixed too.
- Fixed a critical exception in the server loop on 1.16.3 servers.
- Items in your inventory can't be moved anymore when you are in-game.
- Fixed the issue where the leave item didn't work when you clicked a block.

Sorry for the delay and enjoy the update,
Jurian
