Multiplayer Stability Improvements Fixed a potential issue where quick transfer could bypass special container slot logic Quick transfer is now limited to moving items from the player inventory or hotbar into the backpack It no longer forcibly takes items from machine output slots, crafting result slots, reward slots, or special modded slots This reduces the risk of item duplication, item loss, or bypassing other mods’ container logic on multiplayer servers Crafting Table Improvements Fixed drag-splitting inside the crafting utility panel Left-click dragging now evenly distributes items across crafting input slots Right-click dragging now places one item into each slot Double-click collecting now works inside the crafting utility panel Crafting remainder handling has been improved Recipes such as cake crafting now correctly return empty buckets Container-return behavior for vanilla and some modded recipes is now supported Anvil Improvements The side GUI anvil utility now supports more vanilla-like behavior: Experience level cost Item renaming Enchanted book merging Enchantment conflict checks Too Expensive limit handling Item repairing Combining similar equipment for repairs Hidden Utility Data Improvements Crafting, furnace, anvil, and smithing utility data is stored with the backpack If the corresponding upgrade is removed, remaining items are returned to the player If the player inventory is full, remaining items are dropped near the player Server-side cache cleanup has been improved to reduce long-term memory growth on multiplayer servers Requirements Minecraft 1.20.1 Forge 47.x Sophisticated Backpacks Sophisticated Core Curios API, optional JEI, optional Notes This mod is still in beta.
