[Notice : Mirror Dun. Game Crash Upon Skill Replacement] Hello, this is Project Moon. We have identified an issue where, in the Mirror Dungeon, replacing a Skill of an Identity causes the game to crash. ※ As an emergency measure, we have temporarily disabled the Skill Replacement function by forcing it to be “SOLD OUT”. If you are currently within a Skill Replacement UI, any control may cause the game to crash; please restart the game. Cause - As per the UI structure adjustment, we made a unilateral adjustment in the code to universally apply the changes universally. - However, because the Skill Replacement UI in the Mirror Dungeon uses a separate, duplicated version of the UI, the changes did not apply to that specific UI. Solution - We have identified the Mirror Dungeon Skill Replacement duplicate UI and made corrections accordingly. - Because this requires a Client Build, however, a full correction will be deployed with our next Scheduled Update. Future Measures - We intend to no longer use any duplicates of UI if they share similar formats so that they won’t slip through universal changes like these. Also, we are in the process of identifying and analyzing all issues that have occurred after today’s Sep. 19th Scheduled Update. We will inform you via an additional notice as soon as we identify them. We sincerely apologize for the inconvenience.
