- Fixed Low TPS Issues - Spawners no longer stop spawning loot when server TPS drops

🛡️ 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

- 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
