Live's 28th sale to a full buyback removed the oldest item, then sent MoveItemInInventory (inventory 11, VENDOR_BUYBACK) for each of the 26 items left, to slots 0 to 25 in order, before the sold item was added after them. The server left the hole, so the sold item took the dropped item's slot and the buyback page was no longer in sale order. The buyback inventory is not saved and nothing changes hands; only slots move. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
