Paper 1.21.4+

MayorSystem v1.1.7

Fixed

• Fixed a GUI safety issue where shift-clicking menu icons during close/open transitions could leave copied menu items in a player inventory.
• Added managed-menu drag protection for top-inventory slots.
• Improved menu click handling so cancelled inventory actions are synced before follow-up menu actions run.

Upgrade Notes

• No config changes required.
• No permission changes required.
• No database migration required.
