1. Shulker box delivery Players can now place a shulker box filled with the required item directly into the delivery cart. The plugin extracts exactly what's needed and returns the shulker (with any remaining items) automatically
2. Mixed shulker protection Shulkers containing mixed items are rejected on placement, preventing any abuse or accidental deliveries
3. Return to search after purchase After buying an item from the Auction House, players are returned to their search results instead of the main listing page
4. Return to search after delivery After confirming a delivery on an order, players are returned to their search results
5. Price low-to-high default on search Whenever a player searches for something, results automatically sort by lowest price first
6. Accurate delivery notifications Order owners now receive a correct real-time message showing exactly how many items were delivered and the running total (e.g. Mike delivered 32x Grass Block (64/64)), even when multiple players deliver simultaneously
7. Auction sold notification fix Sellers now correctly receive a real-time message when their listing is purchased
