[4.5.1] - 2026-05-20 - Critical Bug Purge III

Fixed

• Turret system completely non-functional — Adventure vs. Legacy API mismatch (BF-16) — The crafting recipe assigned the "Sentry Turret" display name via the Adventure API (meta.displayName(Component.text(...))). TurretListener.isTurretItem() read the name with the deprecated Legacy API (meta.getDisplayName()), which always returns an empty string when the name was set via Adventure — so the check never matched and TurretManager.createTurret() was never called. Placing a crafted turret had no effect. isTurretItem() now reads the Adventure displayName() component first, serialises it to plain text, and falls back to the legacy accessor for pre-migration items.

• onDisable() never called turretManager.cleanup() — turret data loss on restart (BF-17) — CampfireManager.shutdown() was called in onDisable() but the analogous TurretManager.cleanup() call was absent. cleanup() is responsible for cancelling the internal firing task and flushing turrets_data.yml. Turrets placed during a session without a prior auto-save were silently lost on server restart. turretManager.cleanup() is now called from onDisable().

• /zapoc reload wiped all zombie custom AI — missing scanExistingZombies() call (BF-19) — loadConfig() (called by loadAllConfigs() at the start of every reload) called trackedZombies.clear(). ZombieBehaviorTask iterates that collection each tick; after a reload it was empty, so every living custom zombie lost its AI (no moans, no screaming, no sun effect, no mutation) until the zombie died or new ones spawned. scanExistingZombies() is now called at the end of the reload handler to repopulate the map immediately.

• /zapoc reload did not rebuild TurretManager — config changes had no effect (BF-18) — TurretManager reads range, damage, and fire-rate-ticks only in its constructor. After a reload the old instance kept running with stale values. The reload handler now calls turretManager.cleanup() and recreates a fresh TurretManager, matching the pattern already applied to StructureManager.

• Feign-Death zombie permanently invulnerable and AI-less after server restart (BF-20) — When a Feign-Death zombie "died", the code set invulnerable=true and AI=false, then scheduled a BukkitRunnable to revive it after 3–5 s. If the server restarted during that window, the task was discarded but the entity flags persisted in NBT — leaving an immortal, motionless zombie that could never be killed. A new PDC key feign_active is set at the start of feign-death and cleared on revive. ZombieCleanupListener.onChunkLoad now detects this key and immediately invokes the shared SpecialZombieListener.reviveZombie() method, which also handles the scheduled revive path.

• CampfireManager.damageCampfire() triggered a full YAML write on every zombie hit (BF-21) — saveCampfires() (atomic file I/O on the main thread) was called each time a zombie attacked a campfire. With multiple zombies attacking multiple campfires simultaneously during a Blood Moon, this caused significant main-thread stalls. Replaced with a dirty flag: damage marks the campfire data as dirty, and the periodic task flushes to disk at most once every ~5 seconds. Immediate saves are still performed when a campfire is destroyed.

• ZombieBehaviorTask.handleScreamer() read 6 YAML values per zombie per 0.5 s (BF-23) — Every invocation of handleScreamer() called getZombiesConfig().getDouble/getString/getInt() six times. With 20 Screamer zombies that is 120 YAML map lookups per 500 ms. All six values (scream-chance, particle, particle-count, scream-range, darkness-duration, message) are now cached in the same 5-second refresh cycle used by sun-effect config.

• ZombieBehaviorTask.handleBreaker() read success-chance from YAML per zombie per 2 s (BF-24) — zombie-breaking.success-chance was fetched from FileConfiguration inside the per-zombie loop every 40 ticks. Now cached alongside the other task-level values.

• PsychologicalHorrorTask.activeHallucinations used entity ID (int) as map key (BF-25) — Entity IDs are 32-bit integers reused by the server after an entity despawns. Using entity.getEntityId() as the map key could cause stale HallucinationData entries to collide with or shadow new entries sharing the same recycled ID. The key type is now UUID (entity.getUniqueId()), which is guaranteed unique per entity.

• Campfire heal task used 3×3 chunk scan instead of 5×5 (BF-22) — isInsideSafeZone() and onSpawn() were already corrected to 5×5 in a prior release, but the heal loop inside startTask() still searched only 3×3 chunks (~32 block reach). Tier-3 campfires have a 40-block radius, so players near the edge of the safe zone were not receiving the Regeneration effect. The heal loop now uses 5×5, consistent with all other campfire range checks.

Notes

• No config file changes are required. All existing data.yml, campfires.yml, and turrets_data.yml files are fully compatible with 4.5.1.
• Any turrets placed before this update that were saved in turrets_data.yml will load and function normally. Turrets placed during a session that ended with a 4.5.0 server stop without an intermediate save may have been lost — this is the bug being fixed.
