🔧 TheMob v1.8.3_Alpha – Hotfix & Stability Update

This update is a focused stability and behavior refinement hotfix.

Delete boss_template.yml

No new mobs. No power creep.

Instead, v1.8.3_Alpha fixes critical early issues found in v1.8.2 and introduces the first experimental FLEE behavior layer.

🛠 What was fixed ❤️ Health Display & BossBar Stability Fixed multiple long-standing issues where:

❌ Display-health stopped updating correctly

❌ BossBar & health display disappeared after long fights

❌ Health values desynced during long boss phases

Now:

Real-time synchronized updates

BossBar persistence during:

    long combat sessions

    multi-phase bosses

    reload-safe transitions

Automatic re-sync when edge cases occur

Result: Reliable visual health feedback even in extended boss encounters.

🧭 Phase Movement Bug – "Moonwalk Fix" Fixed an issue where mobs (especially bosses) could:

slide sideways

appear to "moonwalk"

drift unnaturally during high-intensity phases
(observed especially in chaotic / desperation phases)

Now:

Corrected velocity application

Stabilized movement vectors during:

    forced AI overrides

    phase-driven ability spam

Eliminated sideways drift artifacts

Result: Natural, readable movement even under extreme combat logic.

🩺 Long-Fight Visual Cleanup Bug Fixed a rare but critical issue where after very long fights:

❌ BossBar disappeared

❌ Health display vanished

❌ UI elements stopped updating

Root cause: Edge-case lifecycle cleanup triggered too aggressively during long runtimes.

Now:

Corrected cleanup triggers

Hardened lifecycle tracking

Added automatic recovery logic

Result: Boss fights remain visually stable for unlimited durations.

🆕 New: Experimental FLEE Behavior (Alpha) Introduced the first version of health-based flee logic.

🧠 Behavior Overview When certain health thresholds are reached, mobs can now:

attempt disengage

reposition strategically

escape pressure zones

break direct combat loops

✨ Features

Health-percentage based triggers

Smooth disengage pathing

Smart target loss handling

Fully AI-driven (no teleport abuse)

⚠ Status: Experimental (Alpha)

Enabled internally only

Still being tuned

Will be expanded in v1.9+

Goal: Create mobs that survive longer, reposition smarter, and feel tactical instead of suicidal.

⚙️ Stability Improvements

Additional safeguards in:

    AI tick loops

    boss phase transitions

    HUD lifecycle handling

Improved fail-safes for:

    stalled visuals

    stuck UI updates

Hardened runtime cleanup safety

Result: Higher uptime reliability & smoother long-session gameplay.

⚠ Notes

No gameplay balance changes

No config changes

No breaking changes

Safe update from v1.8.2

Existing mobs & bosses continue to work unchanged

✅ Compatibility

Paper / Spigot 1.20+

Fully compatible with all existing TheMob configs

Safe for production testing environments

Final Note v1.8.3_Alpha is about polishing the foundations:

Stable visuals Predictable AI Smarter combat flow

This hotfix pushes TheMob one step closer to true next-gen mob intelligence.
