xApocalypse 1.4.3 — Performance & Polish Update

Version 1.4.3 closes the remaining minor findings from the full xApocalypse code audit, focusing on performance, cleanup, compatibility, and small player-facing issues.

Performance improvements

• Combined custom zombie AI and distance-based LOD management into a single world scan.
• Removed the second full zombie iteration that previously ran every half-second.
• Corrected distant custom AI timing so it runs at the intended reduced interval.
• Preserved reliable AI enable/disable transitions as players approach or leave zombies.
• Improved AI restoration during plugin reloads and shutdowns.
• Cached frequently accessed zombie-class behavior settings instead of repeatedly reading the configuration during AI ticks.
• Cached settings are refreshed automatically with /xa reload.

Zombie and spawning cleanup

• Removed unused player-based UndeadSpawner methods.
• Removed the associated UUID tracking map that could otherwise retain unnecessary player data.
• Invalid or outdated stored zombie-class tags are now handled safely instead of potentially throwing an error.
• Removed redundant item metadata access when creating Frost zombie armor.
• Spitter target checks now safely handle world changes.

Zombie Guts and scent fixes

• Fixed dual-wielded Zombie Guts producing a second “already immune” message.
• Main-hand activation is now prioritized when Guts are held in both hands.
• Player scent state is removed when the player leaves, preventing unnecessary offline entries.

Compatibility improvements

• Replaced deprecated attribute enum constants with registry-backed Minecraft attribute references.
• Updated baby-zombie filtering to use the modern Ageable adult-state check.
• Retained compatibility with the existing Minecraft 1.21 plugin target.

Message handling

• Replaced the loose MiniMessage detection heuristic with proper tag-pattern detection.
• Plain messages containing < or # are no longer mistakenly treated as MiniMessage.
• Invalid MiniMessage components now fall back safely to legacy formatting.

Release metadata

• Updated the plugin manifest, Maven build, default configuration, localization file, README, installation instructions, and wiki pages to version 1.4.3.
