+ Fixed dupe with 1.20.2 meteor client & packet delay/quick reconnect. New system will automatically remove the item. You will also be alerted in the console when a dupe item is removed from a player's inventory.
+ Possible fix regarding transaction menu not applying model data correctly
+ Added setting to change which slots items are filled into in the main auction menu, same with the total rows in the game. Over the new updates all the guis will have more customization and will be migrated to a much easier system for dev purposes. Likely in the next update I'll include a setting to opt-in to the new GUI system for the main /ah menu to get feedback.
