Release v1.5.2 - Critical Bug Fix

Critical Bug Fix - Race Condition Crash

🐛 Fixed Race Condition Crash During Back-to-Back Raids

BlueMeter would crash after 2-3 consecutive raids/encounters, especially in passthrough mode with "clear on instance change" enabled.

Error Fixed: System.ArgumentException: Destination array is not long enough to copy all the items in the collection

Root Cause

A threading race condition in DataStorage.cs where the packet processing thread and UI thread were simultaneously accessing DPS data dictionaries without synchronization.

Fix Applied

• Added thread-safe locking (_dpsDataLock) to protect all DPS data dictionary operations
• Protected list creation in cached list properties
• Protected dictionary modifications and clearing operations

Impact

• Eliminates crashes during extended play sessions with multiple consecutive encounters
• Minimal performance overhead from locking
• Fixes instability in high-activity scenarios (raids, World Boss Carnage)

Files Changed

• BlueMeter.Core/Data/DataStorage.cs - Added thread synchronization

Special Thanks

• GitHub user anguyen2015 for reporting the crash with detailed error logs
