Frost Lag Lite

FrostLag Lite 1.0.0 — First release 🎉

The first public release of FrostLag Lite, a lightweight and silent anti-lag plugin for Paper, Spigot and Bukkit.

✨ Features

• Silent automatic cleanup: removes dropped items, XP orbs and arrows stuck in blocks every 10 minutes (every 3 minutes while lagging), with no chat or console messages. Freshly dropped items are protected for 10 seconds.
• /fl auto on|off: turn automatic cleanup on or off in-game. The setting is saved to the config.
• Item merging: identical nearby items are merged into a single stack.
• Mob limit per chunk: 30 monsters / 40 animals / 60 total (15 / 25 / 35 in anti-lag mode). Spawns from plugins, /summon and spawn eggs are never blocked.
• Lag machine protection: per-chunk limits for falling blocks (16), primed TNT (24), minecarts (20) and boats (20).
• Crowded chunk sweep: every minute, removes only the excess items and mobs from overcrowded chunks.
• Automatic anti-lag mode: when TPS stays below 17, it tightens limits, lowers view/simulation distance (Paper) and freezes mob AI in crowded chunks. Everything is restored automatically when TPS recovers.
• TPS monitor: /fl status shows TPS (now / 1m / 5m), MSPT, RAM, CPU and entities per world. /fl top lists the heaviest chunks with coordinates.

🛡️ Protection

• NPCs, holograms, armor stands, displays, item frames, paintings, villagers, named/tamed mobs, mob stacks and custom plugin items are never removed, merged or counted.
• Works with Citizens, FancyNpcs, DecentHolograms, WorldEdit/FAWE, ItemsAdder, Oraxen, MythicMobs, Shopkeepers and any other plugin through generic detection.
