Bug Fixes
【Addendum】
・Fixed an issue with Battle Mounts and Assist Characters where unintended behavior could occur when raising the Awakening Level from the "Awakening Level Unlock" window accessed through the Friendship Panel.
This issue did not occur when raising the Awakening Level by using an item from the Kinchaku.
●When using a Manifestation Scroll or Accord Scroll
The confirmation window that appears after the Awakening Level is raised was not displayed, and the number of scrolls shown in the Kinchaku did not decrease. This was only a display issue, and the correct state would be reflected after logging in again, moving to another field, etc.
●When using Articles of Awakening
The client would forcibly close. The Awakening Level was raised and the Articles of Awakening were consumed correctly, and the correct state would be reflected after logging in again.
・Minor bugs will be fixed.
