1. Achievement System Normalization and Improvements

Platform Sync Fix: Fixed a bug where achievements were not correctly unlocking on the Steam platform. Popup Queue Implementation: Added a sequential notification queue (2-second interval) to prevent overlapping popups when multiple achievements are earned simultaneously. Retroactive Support: The game now scans local save data on startup to automatically sync any achievements that were earned but not reflected on the platform.

2. Traits Saving and Synchronization Bug Fixes

Save Guarantee via ESC/Exit: Enhanced the real-time synchronization logic to ensure data is saved when closing sub-widgets via the ESC key or when quitting the game immediately after spending points. Level Transition Data Preservation: Implemented a forced save before entering the Arena, Training, or Mock Combat to prevent data rollbacks after loading. Notification Dot Optimization: Fixed a UI bug where the red notification dot remained on the hub button even after all trait points were spent.

3. System Stabilization

Mock Combat Reward Prevention:Re-verified and tightened logic to ensure no experience or stat changes are recorded in the save file during mock combat. Save Data Compatibility: Fully compatible with save files from versions prior to v0.0.81.
