ServerBooster v26.1.6

Full Changelog - https://github.com/SrCodexStudio/ServerBooster/releases

Bug Fixes​

• Block Limiter off-by-one fixed — Limits now work correctly. A limit of 4 allows exactly 4 blocks, not 3. This affected all category limits (hoppers,
  chests, crafting tables, enchanting tables, etc.), custom material limits, and entity placement limits (item frames, paintings).
• Block Limiter cache poisoning fixed — Previously, after a denied placement, the count cache could store incorrect values for up to 5 seconds,
  causing additional false denials. Cache is now properly invalidated on every placement attempt.
• Block Limiter deny message now shows accurate count — The message no longer includes the temporarily placed block in its count.
• Hologram checksum migration — Items stacked before this update are now automatically migrated to the new checksum format without data loss.
  Previously, updating could reset stacked items to 1.

Hotfix: Hopper Furnace Behavior + Stability Patches​

Hopper Optimizer Fix​

• Fixed: Hoppers below furnaces were pulling fuel and input items instead of only pulling from the output slot (vanilla behavior)
• Now correctly respects vanilla slot restrictions for all special containers:
  • Furnace / Blast Furnace / Smoker: Only pulls from output slot (slot 2)
  • Brewing Stand: Only pulls from potion slots (0-2), not fuel or ingredient slots
  • Chests, Barrels, etc: Unchanged, pulls from all slots

ServerBooster v3.0.1 [TEASER]
Major Stability & Performance Update

​

What's New in v3.0.1

Comprehensive audit of all 12 modules. 36 issues identified and fixed, including 5 critical memory leaks, 2 exploit patches, and major performance optimizations.



Critical Fixes

• Memory Leak Fixed: The lag machine detector stored direct chunk references in memory, preventing garbage collection. Servers running for hours would see steadily increasing RAM usage. Now stores only coordinates, auto-evicts after 5 minutes.
• Memory Leak Fixed: After /reload, the plugin's background task system would silently stop working. Update checker, entity processing, and other async tasks would fail. Now properly re-creates the task system on every reload.
• Performance Fixed: The VillagerOptimizer copied ALL entities in the world (items, projectiles, mobs) every 30 seconds just to find villagers. On busy servers this caused lag spikes. Now uses server-optimized villager-only lookup.
• Exploit Patched: Players could use pistons to push limited blocks to new positions, bypassing block placement limits entirely. Piston movements now update block tracking.
• Exploit Patched: Explosions (TNT, creepers) destroyed tracked blocks without updating the limiter. Explosions now properly clean up tracking data.

Performance Improvements

• ChunkBlockLimiter: 1,400x faster
  Before: Every block placement scanned 1.44 MILLION blocks.
  After: Uses tile-entity scanning + spatial index + LRU cache.
• HopperOptimizer: No more chunk scanning
  Before: Iterated ALL loaded chunks in ALL worlds every 8 ticks.
  After: Maintains a registry of hopper locations. Only visits known hoppers.
• VillagerOptimizer: Smarter player detection
  Before: Expensive entity search per villager per cycle.
  After: Player positions computed once and reused with simple distance math.
• NMS Reflection: Cached lookups
  Field lookups that ran on every entity tick are now cached at startup.
• EntityOptimizer: Respects VillagerOptimizer
  No longer accidentally re-enables AI on intentionally lobotomized villagers.

Bug Fixes

• Elytra config was never read - Typo in code meant riptide trident settings were always ignored
• /sb info showed 8/12 modules - Missing 4 modules from the status display
• maxItemsPerTransfer had no effect - Config loaded but never used in hopper logic
• Physics detector didn't reload worlds - World list was stuck from first startup
• Physics threshold was mislabeled - Comment said "nanoseconds" but code compared event counts
• Chunk key collisions - Negative coordinates could collide with positive ones
• Particles crashed on 1.20.5+ - Particle names were renamed in newer versions
• Data loss on crash - Block tracking save used unsafe file operations
• Save race condition - Auto-save could lose track of unsaved changes
• Memory leak on world unload - Tracking data stayed in RAM forever after world unload

VillagerOptimizer Improvements

• Profession-only targeting - Only affects villagers with a job (Librarian, Farmer, etc.). Normal villagers and Nitwits are ignored.
• Faster detection - First check runs 1 second after startup instead of 30 seconds.
• Timer no longer resets near players - Previously, standing near a villager would reset the stuck timer every cycle, preventing optimization. Now the timer keeps counting.

Item Stacking (HologramItemManager)

• Despawned item cleanup - Items that despawned naturally left stale data in memory. Now cleaned up every 5 minutes.

Technical Info

• Java: 17+
• Platforms: Paper, Spigot
• Versions: 1.17.x - 1.21.x
