AIC Factory & Regional Development Improvements

• Facility Placement Optimized: You can now place a facility directly if you have it in your Backpack or any depot, or if you have enough materials in any depot to construct it.
• Farming Experience Optimized: Top View mode is now available in farming areas, and planting plots can now be placed tightly together without spacing restrictions. [Fertilization] options allow you to enable Fertilization Assist and configure its settings. Once a fertilizer is selected, operators on your team will use it to fertilize plots.
• New Facility [Auto-Farmer]: Unlocked through side mission [A Painting Open for Business], the [Auto-Farmer] can perform Auto-Germinate and Auto-Harvest in the Farm in [Si's Painting]. As the story progresses, the [Auto-Farmer] will also become available in the farming area of [Wuling City].
• Delivery Job Optimized: Transferred delivery jobs that aren't accepted within a certain time will be picked up and completed by other helpers instead of expiring. When accepting jobs, every region will have plenty of jobs available, so there's no need to keep refreshing or waiting.

Combat Experience Improvements

• Enemy Targeting Optimized: During battle, you can now long-press the lock-on button to bring up a reticle. You can then rotate the camera to aim at an enemy and release the button to lock onto the nearest enemy. Existing targeting and lock-on functions remain available after this adjustment.
• New Combo Skill Priority Settings: For combo skills that activate at the same time, you can now adjust their trigger order in the [Team] screen.

Progression Experience Improvements

• LTO Sanity Meds Auto-Use Upon Expiration: A new Auto-Use feature for LTO Sanity Meds has been added. When LTO Sanity Meds expire, they will be auto-converted into Sanity. If the Sanity limit is reached, the excess will be converted into [Sanity Essences] using [Sanity Extractors]. Sanity Essences do not expire. If the Sanity limit is reached and you can't hold any more [Sanity Essences] or have no [Sanity Extractors] available, any remaining LTO Sanity Meds will be destroyed.
• New [Gear Plan] Feature: Save and name multiple gear plans to better suit operators in different lineups.
• Quick Gear Assembly for Artificing: The gear assembly process during artificing has been optimized. On the [Select items to consume] page, a new [Assembly] tab has been added that automatically filters for gear that can be used as artificing material. You can either manually adjust the amount or use Auto-Fill to quickly assemble the gear required and use it for artificing, without having to switch between pages.

Interactions and Quality-of-Life Improvements

• Clue Collecting and Gifting Optimized: In [Control Nexus Task], you can now collect and fill clues gifted by friends with one click, in addition to the existing one-click option for collecting local clues. Duplicate clues can also be gifted to friends with one click.
• New Shift Rotation Feature: Each cabin can have up to two operator shifts (A and B). Use [Activate Shift] to change shifts manually, or [Auto-Rotate] to switch shifts automatically according to the work schedule. Please note that cabin production may be halted if the estimated work time of a shift cannot cover the work schedule.
• Friend Visit Experience Optimized: You can now use the [Visit Next] button or its shortcut to directly go to the next friend's ship.
• Operator Display Optimized: New visual effects have been added to the [Friends List] and [Profile] screens for max-potential 6-star operators. Max-potential 6-star operators will also display their special effects when walking around Dijiang.
• Camera Sticker Optimized: New support has been added for rotating and scaling stickers, placing multiple stickers at once, and clearing all placed stickers with one click.
• Controller Support Optimized: Controller support has been optimized for progressions, delivery jobs, stage results, and other features. This covers interfaces such as [Operator - Overview], [Operator - Ability Matrix], [Operator - FILE], [Weapon - Potential], [Regional Development - Depot Node], making interactions more convenient.

Graphics Improvements

• Environmental Detail Optimized: Some fallen leaves in the environment are no longer just static decorations. They now move and drift in response to operator movement, skill use, and wind. Our hope is to let players on all platforms, including mobile, enjoy richer interactions between the environment, operators, and skills.
