Hello, this is Project Moon.

We have identified that incorrect information was included in the July 17th Scheduled Update notice, and we would like to correct this error.

- Original Notice
▶ Added unique Announcer voiceline conditions for Tiphereth and Magical Girl (The Queen of Hatred)
※ Please note that these can be skipped by tapping/selecting the screen after the combat Encounter ends; we are planning on adding an option in the settings menu to skip these automatically.

- Corrected Notice
▶ Added unique Announcer voiceline conditions for Tiphereth and Magical Girl (The Queen of Hatred)
※ Please note that these can be skipped by tapping/selecting the screen after the combat Encounter ends.

While these lines can be skipped post-update by touching or clicking on the screen after the encounter is over, it has been confirmed internally that nothing has been decided regarding adding an option to automatically skip these lines or other kinds of adjustments regarding this change.

There was a human error in the process of discussing these changes and writing the notice; internally, there was a misunderstanding that the option to automatically skip the dialogue would be added, which made it into the notice itself.

If any additional adjustments regarding the said Announcers will be added in the future, we will inform you again via a Scheduled Update notice.

We sincerely apologize to all users who have been waiting to see this adjustment.

We will put further care into writing our update notices so that no similar mistake will occur again in the future.

Thank you.

Hello, this is Project Moon.

In Version 1.82.0, updated July 17th, we have identified an issue where the 'Restore Purchase' button does not work under certain circumstances, and have addressed it.

[Issue]
When attempting a purchase through Steam, upon failing to communicate with Steam servers, the 'Restore Purchase' button does not work

[Cause]
Upon communication failure with Steam, due to the response value being changed, the error flagging function did not work

[Solution]
Fixed the logic that was causing the issue

This issue has been resolved without a separate client update or an in-game resource download.

We sincerely apologize for the inconvenience.

Hello, this is Project Moon.

We would like to inform you about information that was missing from our July 14th Scheduled Update notices.

Please continue reading for more information.

• Fixed an issue where, in certain circumstances, UI controls become unavailable when entering Mirror of Immortality

※ This issue occurred with the July 10th Mirror of Immortality Hard Difficulty.

※ Vergilius Announcer, previously distributed via the 2nd Anniversary Event, will be added to the list of extractables available from Walpurgis Night.
※ With the addition of Vergilius Announcer to Walpurgis Night extractions, the Announcer can now be obtained from Yisang Exchange as well.

<Extractions in which Vergilius Announcer is either featured or obtainable from Yisang Exchange>

Hello Project Moon fandom =)

PM 9th anniversary is on November 18th, and I'd like to organize something to celebrate! I have two options in mind:

a. A fan exchange (you sign up to create a gift for another participant, with every gift revealed on the anniversary day)
b. A fan week (a week of daily prompts around the anniversary to inspire creation)

Does one of these sound better than the other?

(If you have your own idea but don't feel confident pulling it off alone, I'm open to discussing it too ;) )

Hello, this is Project Moon.

We have identified an issue where, in Version 1.81.0 and 1.81.1, updated July 3rd, the Starlight summary post Mirror Dungeon completion would sometimes show "0 Starlight used".

[Issue]

• An issue where, sometimes, Starlight that was used does not count as used Starlight

[Cause]

• An issue with the Starlight acquisition & spending formula in certain circumstances

[Solution]

• Addressed the problematic logic

This issue has been resolved without a separate client or in-game download; we verified the player logs to identify the affected cases.

Starlight will soon be withdrawn from affected accounts in the near future.
Please note that, in that process, you may lose the sum of Starlight that was mistakenly calculated as zero.

We will inform you via an additional update regarding a more detailed schedule of when this will take place.

We sincerely apologize for the inconvenience.

Hello, this is Project Moon.

After the 1.81.0 Scheduled Update on July 3rd, we have identified an issue where some managers are unable to play the newly updated Mirror Dungeon - Mirror of Immortality.

We have identified the cause of this issue. We are currently working on fixing this issue, and the update to Version 1.81.1 with the fix will be deployed at 2025.07.03 18:00 (KST).

Fortunately, the respective market reviews of the update were completed early this time. Please update the game on Steam or your choice of mobile device to play the game normally.

If your respective store does not display the button to update the game, please note that there may be a margin of error based on your device settings, and try again at a later time.

We sincerely apologize for this progression issue.

[Issue]

• An issue where, after the 2025.07.03 Scheduled Update, starting Mirror of Immortality in Version 1.81.0 fixes its difficulty to "Hard difficulty" making it impossible to progress past that point

[Cause]

• This issue can be caused if, in their final playthrough of Mirror of the Dreaming, 1) the player activated the "Parallel Superposition(Infinite) mode", and 2) progressed past Floor 6.
• To be more specific, this is a logic error that occurred while processing data that was carried over from the previous Mirror Dungeon.

[Solution]

• Address the problem logic

[Future Measures]

• In future Mirror Dungeon updates, we will add more specific test cases to test if newly updated functions interfere with preexisting functions

Once again, we sincerely apologize for the inconvenience.

[7/3 Scheduled Update Error Compensation]

• Content : Lunacy x750
• Recipients : All users whose game accounts were created before 10:00 July 10th, 2025 (KST)
• When : After July 3rd, 2025 (Thu) 18:00 (KST)
• Can be claimed once per account

ErrorCompensation can be claimed until July 10th, (Thu) 2025, 10:00 (KST) via the in-game Mailbox. (Mail available for 7 days)

Hello, this is Project Moon.

The following are more detailed information regarding the Mirror of Immortality Progression Issue identified in Version 1.81.0.

[Issue]
After the July 3rd Scheduled Update, entering the Mirror Dungeon does not show the Theme Packs, preventing players from progressing through the Mirror Dungeon

[Cause]
This issue can be caused if, in their final playthrough of Mirror of the Dreaming, 1) the player activated the "Parallel Superposition(Infinite) mode", and 2) progressed past Floor 6.

We have identified the exact logic of the issue, and we are currently making adjustments and running tests to fix the issue.

We will share the exact deployment ETA of the fix with an additional update.

We sincerely apologize for the inconvenience.

Hello, this is Project Moon.

After the 1.81.0 Scheduled Update, we have identified an issue where some players are unable to play the newly updated Mirror Dungeon - Mirror of Immortality.

We are currently investigating this issue and will provide an update as soon as more information becomes available.

We sincerely apologize for the inconvenience.

Announcement on Steam.

Hello, this is Project Moon.

There was a missing bug fix from our last Scheduled Update notice.

Please continue reading for more information.

1. Fixed an issue where The Thumb East Soldato II Sinclair does not count toward meeting certain Achievements & E.G.O Gift conditions
   ※ Relevant Achievement: Clear Mirror Dungeon at Floor 5 or higher with 5+ Identities that use certain Keywords
   ※ Relevant E.G.O Gift Conditions: Encounter Start: Activates when there are 5 or more Identities with Attack Skills that inflict certain Keywords

※ - Mirror Dungeon Keyword checker data was missing for The Thumb East Soldato II Sinclair's Identity Data, and we failed to catch the issue where this caused the Identity's Keywords to not count toward meeting certain Achievements and E.G.O Gift conditions.

We identified this issue as we were writing the Scheduled Update notice on June 30th, and sought to deploy a Hotfix immediately.

However, as our market submission was already complete, the client build is currently in standby; this means that this issue cannot be corrected via a hotfix, and can only be fixed with a Scheduled Update on July 3rd.

We sincerely apologize for the inconvenience.
