( Issue Details )
– This issue can be caused by forfeiting immediately after entering the Boss Encounter, then re-entering with a different Team loadout
1. Even after re-entering with a different loadout, because the game reads the previous Team loadout instead, Achievements that should be (or shouldn't be) completable with the current loadout are not completed (or completed)
2. Loadout Achievements with "Not counting Backup Units" condition count Backup Units for the purpose of completing them
( Issue Cause )
– When re-entering an Encounter after forfeiting it, the in-game data used for Achievement tracking does not properly update with the user's current Team loadout, causing this issue to occur.
( Issue Solution )
– Additional code was inserted to update the in-game data used for Achievement tracking. This solution will be deployed via a hotfix.
[ Hotfix ETA ]
– 3.27(Fri) 16:00(KST)
– There may be a 10 minute delay.
※ The Hotfix will be deployed upon restarting the game, and does not require a separate client update. However, please note that additional in-game downloads may occur.
[ Issues to be resolved with a Scheduled Update ]
▶ An issue where certain Encounters are missing BGM and connected lyrics
▶ An issue where the Mirror Dungeon EXTREME Theme Pack 'Bridle of Infinity' enemy unit's "Surgery" Keyword does not work
※ The above issues will be resolved with the April 2nd Scheduled U pdate.
We sincerely apologize for the inconvenience.
