[Current Known Issue]
■ In the seasonal event quest "In the Dark of Night", in rare cases the quest instance battle will not complete and the event will not progress when the boss is defeated at the moment the boss's attack phase switches.
Upon investigation, we found that the program causing the issue is very complex and would take a considerable amount of time to resolve.
As a result, it will be difficult to fix the problem during the collaboration event.
If you encounter this issue during the quest instanced battle "In the Dark of Night", please kindly logout or wait until the time limit forces you out of the instanced area before attempting to restart the quest instance battle again.
We sincerely apologize for any inconvenience this may be causing and thank you for your understanding.
