Auction House Cobb

Changelog - 1.8.0

Added

• Mailbox System: Added a /ah mail command and a dedicated Mailbox tab in the main interface. All expired and cancelled Pokémon or items are now sent to a secure player mailbox database (auction_house_mailbox.json) instead of being pushed directly to the PC or inventory. This ensures zero items or Pokémon are lost even if the player is offline or their inventory/PC is completely full.
• Dedicated Transaction Log: Added a dedicated server-side transaction logging file (logs/ah_transactions.log) to track all listings, purchases, cancellations, and mailbox claims with detailed timestamps.

Improved

• Transaction Safety: Rewrote transaction fallback logic and integrated mailbox routing for both Pokémon and items to prevent duplications or inventory loss.

Changelog - 1.6.5

Fixed

• Fixed Pokémon being permanently lost if a listing expired while the seller's PC was full.
• Fixed race conditions and inventory rollback failures that could cause item or money loss during transactions.
• Fixed malformed NBT items converting into blank items instead of canceling the transaction.
• Fixed listings jumping to the end of the page when a purchase fails.
• Fixed modded clients being able to create listings or offers with zero or negative prices.

Improved

• Removed unnecessary thread locks (synchronized blocks) to eliminate server lag spikes during high AH traffic.
• Optimized the trade history pruning to use instantaneous LinkedList operations instead of heavy Array recalculations.
• Added automatic .bak safety backups for all JSON database saves to prevent total corruption during server crashes.

Changelog - 1.6.4

Fixed

• Fixed item auction listings sometimes deleting the item without paying the seller.
• Fixed cancelled item auctions sometimes removing the listing without returning the item.
• Fixed item purchases where the buyer could complete the transaction without the seller receiving payment.
• Improved item auction transaction safety with better rollback handling when payment, delivery, or inventory insertion fails.
• Item auction listings now save their full item data, preventing listed items from becoming unrecoverable after a server restart.

Changelog (1.6.3)

Fixed

• Critical: Item Data Loss: Fixed a major bug where item enchantments, custom names, and components were lost when sold in /ahi. Now fully compatible with Minecraft 1.21.1.
• Critical: Duplication Glitch: Fixed race conditions that allowed multiple players to buy the same listing. Transactions are now atomic.
• Thread Safety: Added synchronization to auction listing operations to prevent concurrent modification errors.

Changelog (1.6.2)

Added

• Buy Confirmation Dialog: Added a confirmation screen when purchasing items through /ahi.
• Item History Persistence: Trade history for items is now saved in auction_house_item_trades.json.

Fixed

• Item History Display: Resolved an issue where the item history tab was displaying raw translation strings.
• Localization Errors: Fixed missing translations for trade types and formatted history lines with proper details.

Changelog (1.6.1)

Added

• Item Auction House History tab (/ahi)
  • New History tab in the Item Auction House screen.
  • Server-side storage of item trade history (recent actions, capped).
  • New network packets:
    • RequestItemTradeHistoryPayload
    • ItemTradeHistoryPayload
  • Client renders the history list for the player.

Changed

• Pagination improvements for /ah and /ahi

  • Pagination is now server-driven and kept in sync after actions.
  • The server no longer forces a refresh back to page 1 after buy/create/remove/price update actions.
  • The client now refreshes the current page after receiving an ActionResult (keeps your page instead of resetting).
  • Opening /ah and /ahi now requests listings using the screen’s current pagination state (instead of hardcoding page 0).

• Page size reduced

  • /ah (Pokémon AH): 9 listings per page
  • /ahi (Item AH): 9 listings per page

Fixed

• Fixed cases where pagination buttons appeared to “not work” because the listings refresh was being reset to page 1 after actions.
• Fixed issues where /ah and /ahi could fail to open correctly due to client/server listing request flow inconsistencies.

Changelog (1.5.3)

Item Auction House (/ahi)

• Added mouse wheel scrolling in the Item Auction House listings.

Changelog (1.5.2)

Fixes

• Fixed disconnect/kick for some players when opening the Auction House
  • Error seen: EncoderException: Failed to encode packet ... custom_payload (auction_house_cobblemon:listings)
  • Root cause: the listings packet could become too large because it embedded the full Cobblemon pokemon JSON for every listing.
