EcoXpert - Changelog v1.3.1
Version 1.3.1 - Bug Fixes & Stability
Release Date: January 8, 2026 Compatibility: Minecraft 1.19.4 - 1.21.11 Java Version: 17+

Bug Fixes
SQLite Database Lock Fix

• Problem: SQLITE_BUSY - database is locked error under concurrent operations
• Solution: SQLite pool size reduced to 1 connection to serialize writes
• Details:
  • SQLite only allows one writer at a time
  • HikariCP pool was configured with 10 connections causing conflicts
  • busy_timeout increased to 30 seconds as safety net
  • MySQL pool remains at 10 connections (handles concurrency properly)

SQL Compatibility Fix

• Problem: INSERT OR IGNORE syntax only works in SQLite, not MySQL
• Solution: Database-specific SQL syntax detection
• Details:
  • SQLite: INSERT OR IGNORE INTO...
  • MySQL: INSERT IGNORE INTO...
  • Affected files: EconomyManagerImpl.java, MarketManagerImpl.java

Market GUI Click Handler Fix

• Problem: Clicking "Sell Hand by $" button sent "hand" to chat instead of opening sub-GUI
• Solution: Reordered event handlers to check sub-GUI title before marketInv == null
• Details:
  • Sub-GUI was not tracked in openGUIs map
  • Handler returned early without cancelling the event
  • Same fix applied to MarketOrdersGUI.java

Missing Translation Keys Fix

• Problem: Translation keys displayed as raw text (e.g., market.gui.sell-hand.lore1)
• Solution: Added missing keys to correct YAML paths
• Added keys:
  • market.gui.sell-hand.* (title, amount, lore1, lore2)
  • market.gui.bedrock.action.* (19 keys for Bedrock action GUI)
• Files: messages_en.yml, messages_es.yml

Translation System Fallback Improvement

• Problem: New translation keys not available if user has old language files
• Solution: Improved fallback to always check embedded JAR resources for missing keys
• Details:
  • Local files are checked first (preserves user customizations)
  • If key not found, automatically loads from JAR embedded resources
  • Added UTF-8 encoding for proper character support
  • Debug logging for troubleshooting translation issues

GUI Item Theft Prevention

• Problem: Items in GUIs could be moved to player inventory when translation keys failed
• Solution: All GUI click handlers now check both translated title AND raw key
• Affected GUIs:
  • MarketGUI: List GUI, Sell Hand sub-GUI
  • MarketOrdersGUI: Orders list, Select quantity
  • LoansGUI: Offer preview, Schedule
