[Player / Leveling] Health drops/caps at ~50% upon leveling up

Description:

There is an issue with player health update mechanics upon leveling up.

Health Drop: If a player levels up while having high health (e.g., above 70%), their health percentage drops down to 50% or less instead of preserving their current percentage relative to the new health pool.

Missing Full Heal/Mana Recovery: Unlike standard WoW mechanics (both retail and WotLK/Blizzlike private servers) where leveling up fully replenishes health and mana to 100%, the character’s health is capped at around 50%.

Expected Behavior:

Leveling up should fully restore health and mana to 100%.

At minimum, leveling up should never decrease the player’s health percentage.

Current Behavior:

Player health gets reduced to ~50% if leveling up with more than 70% health.

Health does not recover to 100% upon gaining a level.
