🐛 Bug Fixes

Spawner Mechanics

• Fixed Cycle Skipping - Resolved issue where spawners would skip a cycle after stack size updates (stacking or destacking)
• Fixed Hopper Integration - Hoppers now continue working correctly after spawner stacking operations
• Fixed Low TPS Issues - Spawners no longer stop spawning loot when server TPS drops
• Spectator Mode Fix - Spectator players can no longer activate spawners

🛡️ Security & Stability

Critical Fixes

• Fixed Item Duplication Exploit - Implemented comprehensive item duplication exploit patch with transaction locking and atomic operations for "Drop All" and "Take All" buttons in spawner storage GUI
• Enhanced Exception Handling - Added exception catching to prevent plugin shutdown when other plugins crash, ensuring SmartSpawner continues to load even if other plugins fail

🎨 Configuration Changes

Placeholder System Update

• New Placeholder Format - Changed from %placeholder% to {placeholder} syntax
• Added Percentage Placeholders - New percentage-based placeholders available in holograms and spawner info buttons

⚠️ Important: You must update your language folder. Backup your current language files and either:

• Delete the language folder to let the plugin regenerate it with new format, or
• Manually update placeholders if using custom language files

Configuration Migration

• Migrated from mob_drops.yml to spawners_settings.yml - Consolidated configuration structure
• Customizable Mob Head Textures - Users can now edit mob head texture displays directly in spawner GUI settings

⚡ Performance Optimizations

Spawner System

• Optimized Range Checking - Significantly improved performance of spawner range detection
• Enhanced GUI Updates - Streamlined spawner GUI view updates with reduced meta calls and improved placeholder handling
• Loot Spawn Optimization - Enhanced loot spawning efficiency with scheduled spawn time tracking and early loot addition

User Experience Improvements

• Accurate Countdown Timer - Spawner delay now counts down correctly from configured time to 00:00 (e.g., 25s → 00:25 to 00:00)
• Smoother GUI Experience - Pre-spawner loot processing for faster, smoother GUI timer performance
• Prewarm Head Texture Cache - Reduced GUI latency by preloading mob head textures
