Issue Fixes
Agents & Enemies
- Fixes an issue with Agent Banyue's Mindscape 01: Greed Burns Like Fire where, in solo combat, after using Basic Attack: Crushing Peaks for the first time on an enemy and increasing their Stun duration, when that enemy exits the Stunned state and the skill hits them again while Stunned, the Daze duration increase effect was not working correctly.
- Fixes an issue where Agent Yixuan's Basic Attack: Cirrus Strike could cause abnormal displacement effects when activated from a further distance away from enemies during combat.
- Fixes an issue where the weapon of Agent Hoshimi Miyabi could display visual abnormalities when performing attack skills in combat while equipped with the W-Engine Hailstorm Shrine.
- Fixes an issue where Agent Ye Shunguang's visual effects could appear abnormal in certain circumstances.
- Fixes an issue where, when Agent Ye Shunguang is equipped with the W-Engine Cannon Rotor, the DMG number color of the W-Engine Cannon Rotor's effect Oversized Barrel is mistakenly shown as the color of Honed Edge DMG in combat after Ye Shunguang enters the Enlightened Mind state.
- Fixes an issue where, after Agent Alice is defeated in combat, the Physical DMG number dealt to enemies by her Core Passive: Twin Rainbows of the Swordheart could display abnormally. This issue is a display issue and does not affect the actual skill effect.
- Fixes an issue where visual effects anomalies could occur after Agent Lucia activates Ultimate: Charge, Great Armor!.
- Fixes an issue where, under certain circumstances, Agent Soldier 11 might not properly execute the 5th hit of Basic Attack: Fire Suppression after awakening her Potential.
- Fixes an issue in combat where, when Agent Astra Yao activates her Special Attack Idyllic Cadenza, hits an enemy, and triggers a Quick Assist to switch to the next Agent, manually swapping in an off-field Agent in an Aftershock attacking state (such as Yuzuha) will result in the new on-field Agent being temporarily unable to properly block enemy attacks or take damage.
- Fixes an issue where, under certain circumstances, some Agent models, visual effects, and camera behavior would display abnormally.
- Fixes an issue in Hollow Zero where, after activating Potential Vision and equipping the Arctic Hunt Gear, Agent Ellen could potentially fail to trigger her EX Special Attack again when hitting enemies marked with Hunting during combat.
- Fixes an issue where controls could become unresponsive during combat in the Cooperation Exercise: Vivian stage.
- Fixes an issue where Agent models might display abnormally after switching Outfits in the Outfit Preview interface.
- Fixes an issue where some Agents' visual performance is abnormal during certain parts of the story.
Systems
- Optimizes shader loading logic for iOS devices. After shaders are fully loaded, this will reduce stuttering and lagging on iOS devices in certain situations. Shader loading time during first-time installation and game version updates will increase based on device performance, with different devices requiring different amounts of time.
- Fixes an issue where interface display abnormalities could occur when jumping to the W-Engine selection screen from the Compendium.
Gameplay
- Fixes display issues with certain icons in Hollow Zero.
- Fixes an issue in Hollow Zero where Agent Ye Shunguang's Special Attack icon could display incorrectly.
- Fixes an issue in Hollow Zero where Agents could spawn in abnormal positions after entering certain scenes.
