Hello Lumia Island Survivors,

As previously announced, the ER X GGST Episodes were intended to be unlockable only for the duration of the collaboration. However, we found that some players were still able to unlock the episodes after the event had ended.

After identifying the root cause of the error, we have implemented a fix, and the episodes are no longer unlockable as originally intended.

■ ER X GGST Episode Availability
- Tuesday, December 23rd 2025 to Thursday, January 22nd before maintenance (UTC)

We will be retrieving the rewards received from unlocking episodes outside of its availability period.

Additionally, we will be refunding the A-Coin spent to unlock these stories to your in-game mailbox.

We apologize for the inconvenience and any confusion this may have caused.
