SmartSpawner

SmartSpawner - Version 1.5.0

🚀 Major Changes

• Migrated to Paper Plugin system with modern Brigadier command framework for better performance and compatibility~~~~
• Support RemoteConsole (RCON) execution for all commands from plugin
• New Prices Command & GUI - Added GUI for viewing spawner item sell prices by shop/custom prices (/ss prices)

🔧 Core Improvements

• Enhanced Spawner list GUI
  • Sort order now displays in descending order
  • Add new admin features: remove spawner, increase stack size, open spawner GUI in admin view, teleport to spawner
• Improved Timer Display - Spawner info now uses %time% placeholder for dynamic updates with better performance
• Enhanced Reload Command - Now properly loads config (range,min-mobs,max-mobs,..) for existing spawners in the world

🐛 Bug Fixes

• Fixed shift-click spawner placement - No longer consumes spawner items when placing in restricted regions (from third-party plugin support)
• Fixed BentoBox integration - Resolved issue where spawners were blocked even outside of islands
• Fixed IridiumSkyblock integration - Removed debug messages spam
• Fixed spawner experience preservation - XP no longer incorrectly persists after server restart

🔒 Critical Security Fix

🚨 MANDATORY UPDATE - Spawner Duplication Exploit Patched

• Issue: Critical vulnerability allowed cheaters and hackers to duplicate spawners using GUI packet manipulation and load/save state exploits
• Root Cause: SpawnerStackerHandler.handleStackDecrease() didn't validate spawner block existence before destacking
• Solution: Added comprehensive ghost spawner validation and packet state verification before processing any destacking operations

⚠️ ALL USERS MUST UPDATE to prevent exploitation of this duplication bug.
