Market and/or Inventory bug (item vanished)

[Striker]

This may be 2 bugs in one; one market and/or mail related, as well as an item vanishing from inventory.

These should be nearly every step I performed:

• bought 2x "quality jute bag" (12 slot) on the market in Tursh seller name I believe was "Dim"
• received 2 mail entries, and i inspected both without taking the items
• right-clicked the item in mail
• item appeared in main inv slot 1
• closed the window without deleting
• opened second mail, did not have an item attached (potential bug)
• closed second mail
• opened first mail, clicked delete
• opened second mail, still no item
• deleted second mail
• only one bought bag (of 2) appeared in inv
• emptied items from first bag slot (Empty Cookie Jar)
• unequipped Empty Cookie Jar from bag slot 1
• equipped jute bag

*** continued to play for a short bit ***

• later; received quest item in my bags (I believe in main inv slot 2)
• moved quest item from main inv slot 2 to main inv slot 1
• quest item appeared in slot 1, bag appeared in slot 2
• emptied second bag (Empty Cookie Jar)
• unequipped Empty Cookie Jar from bag slot 2
• attempted to equip jute bag to bag slot 2
• jute bag in bag slot 1 moves to bag slot 2
• bag slot 1 now empty
• a jute bag still appears in main inv slot 2
• right-click jute bag in main inv slot 2
• jute bag in bag slot 2 closes
• right-click again
• jute bag in bag slot 2 opens
• moved quest item over bag in main inv to see if display bug
• items trade places in main inv
• exited client to force it to retrieve state from the server
• reconnect
• both bag in slot 2 and bag in main inv were gone
• moved quest item through several slots in main inv to see if display bug occurred again, but seemed normal again
