Alpelo object system backport functionality - Better config file handling and structure +- Comprehensive production logging for save operations (warehouse, Koryo points, savedata, Hunter Navi, plate equipment) +- Disconnect type tracking (graceful, connection_lost, error) with detailed logging +- Session lifecycle logging with duration and metrics tracking +- Structured logging with timing metrics for all database save operations +- Plate data (transmog) safety net in logout flow - adds monitoring checkpoint for platedata, platebox, and platemyset persistence ### Changed - Improved config handling +- Refactored logout flow to save all data before cleanup (prevents data loss race conditions) +- Unified save operation into single `saveAllCharacterData()` function with proper error handling +- Removed duplicate save calls in `logoutPlayer()` function ### Fixed - Config file handling and validation +- Fixes 3 critical race condition in handlers_stage.go. +- Fix an issue causing a crash on clans with 0 members. +- Fixed deadlock in zone change causing 60-second timeout when players change zones +- Fixed crash when sending empty packets in QueueSend/QueueSendNonBlocking +- Fixed missing stage transfer packet for empty zones +- Fixed save data corruption check rejecting valid saves due to name encoding mismatches (SJIS/UTF-8) +- Fixed incomplete saves during logout - character savedata now persisted even during ungraceful disconnects +- Fixed double-save bug in logout flow that caused unnecessary database operations +- Fixed save operation ordering - now saves data before session cleanup instead of after +- Fixed stale transmog/armor appearance shown to other players -
