MailboxGUI v3.1.1

This is a small maintenance update focused on the Citizens NPC selector flow, bundled language cleanup, and config comment cleanup.

Added

• Added left-click cancellation while in NPC selection mode.
• Left-click cancel now works for both:
  • Set Post Office NPC
  • Remove Post Office NPC
• Added a new language key:
  • admin-npc-selector-cancelled

Changed

• NPC selector prompts now explain that admins can right-click an NPC to select it or left-click anywhere to cancel.
• Admin NPC Tools GUI lore now includes the left-click cancel instruction.
• Bundled language files were updated to file-version: 3.
• Cleaned and corrected NPC setup/removal wording across bundled language files.
• Removed the plugin version line from the top comment area of config.yml.

Fixed

• Fixed admins/players being stuck in NPC selection mode if they could not successfully update or remove an NPC.
• Fixed NPC selection mode not having a left-click cancel path.
• Fixed missing or incorrect NPC selector language text in several bundled language files.

Upgrade Notes

• No mailbox data reset is required.
• No config reset is required.
• config-version was not changed because the config structure did not change.
• Existing language files using file-version: 2 will upgrade to file-version: 3.
• The language upgrader updates old default NPC selector text while preserving customized server language edits.

Compatibility

• Minecraft/server compatibility remains unchanged from the previous 3.1.x release.
• Citizens is required for Post Office NPC features.
• Vault is only required for economy mail features.
• Dynmap remains optional for map marker support.
