This update has now fixed an issue that I found with players not being able to edit their own inventories. I have also slightly altered some of the text that appears as lore with the items to add more information.

If you discover any other issues with the plugin, please do send me a message or leave a post on the forum post with your issue and I'll try my best to assist you.

Change-log:
Streamlined the code.
Fixed player inventory bug.
Fixed potential 'NullPointerException' that could occur in the console upon clicking on empty slot.
Added lore to the Action menu items.
Improved the player's stats lore.
