Announcement on Steam.

Hello, this is Project Moon.

We have identified an issue where, following the May 28th, 2026 Scheduled Update, persistent stuttering issues are observed in-game.

[ Suspected Cause ]
With the Ver. 1.106.0 Update, the game development engine has changed, and some of the preexisting system that converts Limbus Company characters' Skills, Coins, and Buff effects may have become incompatible with the updated game engine, causing the stuttering issue.

Primary sources of stuttering reports have been identified in the following areas:

• Moving between nodes in the Mirror Dungeon
• Making choices and running Skill checks in Mirror Dungeon Choice Events
• Making purchases in Mirror Dungeon shops
• Selecting Combat Encounters and viewing the pre-battle enemy info UI (Refraction Railway, Story Combat Encounters, Mirror Dungeon Combat Encounters, etc.)

[ Issue Fix ]
We have identified, in areas affected by stuttering, the specific logic that requires optimization. We have made the necessary corrections and are currently running tests to ensure its stability.

[Fix Schedule]
We are working to deploy a version that resolves the stuttering issue as part of the Jun. 4th Scheduled Update.
If the work is completed sooner, we will deploy the fix on the Steam platform first, as it does not require a separate review process.

We sincerely apologize for the inconvenience.

Hello, this is Project Moon.

We would like to inform you about the known issues identified after the May 28th, 2026 Scheduled Update, and the ETA for a Hotfix that addresses some of them.

※ Relevant Skill : The Descending Pin
– Before : [Clash Win] Spawn "Flower-burying Pin" next turn

[ Hotfix ETA ]
– May 28th (Thu) 19:30
– There may be a 10 minute delay.

[ Additional Issues Still Being Investigated ]

▶ An issue where, in Refraction Railway Line 6, certain triggers could cause the turns to pass indefinitely, causing the battle to become unresponsive

▶ An issue where, in Refraction Railway Line 6, The House of Spiders: The Index Nursefather Yi Sang using Furioso-Replica on a certain enemy could cause the game to become unresponsive mid-animation

▶ An issue where Limbus Company's App icon appears differently

If you would prefer a monetary refund instead of Paid Lunacy, please contact Apple Customer Support via the link below to proceed.
Please note that relevant purchased packages will be withdrawn from your account if a refund is processed.

Announcement on Steam.

Hello. This is Project Moon.

As of May 28th, 2026, 00:00 (KST), the prices of packages sold on the Korean App Store have increased.
In order to adjust the prices of the affected packages, sales of certain packages will be temporarily suspended.

At present, we are using the US Dollar (USD) as the base currency for in-app purchases.
In accordance with Apple's policy, package prices for Korean Won (KRW) payments were automatically increased on May 28th due to price equalization with the base currency.

For the affected packages, we plan to resume sales after adjusting the KRW prices on the App Store to match the package prices on Steam and Android.

We will proceed with this correction as quickly as possible. Once the correction is complete, we will provide another notice outlining the follow-up measures.

Please refer below for more information.

Announcement on Steam.

Hello, this is Jihoon Kim, Director of Project Moon.

This notice is meant as an apology, as well as an explanation regarding the Mirror World separation issue in the Identity Story for Blade of the House of Spiders Ryōshū.

Allow me to begin by saying that, in the initial design stage, the story of Season Highlight Identity for Ryōshū was set in the same Mirror World as the other House of Spiders Nursefather and Apprentice Identities.

Internal discussions have been ongoing about whether we should completely separate the two Mirror Worlds and develop their stories independently. During this process, communication between the implementation team and the scenario team was not made clear enough.

In the concluding stage, as I was writing the flavor text, I had decided to group Blade of the House of Spiders Ryōshū and the other Nursefather and Apprentice Identities into the same World. This was conveyed to the scenario team, but not to the implementation team. As a result, the Mirror Worlds grouping was recognized as a bug, and a hotfix was applied to separate the Mirror Worlds in the Identity Stories:

1. Highlight Identity of Ryōshū and the other House of Spiders Identities were initially set to be in the same World
2. During the early part of Chapter 9, while designing and developing Highlight Ryōshū, a brief discussion took place regarding the feasibility of making her story part of a different World from that of the other House of Spiders Identities
3. With the release of House of Spiders Nursefather and Apprentice Identities, I naturally came to think that Highlight Ryōshū’s Identity Story should be set in the same world. The Identity Story and the flavor texts, then, were written with that consideration in mind.
4. The process described in Point no. 3 happened gradually, and it was not decisively shared with the implementation team
5. Following today's Scheduled Update, the implementation team saw that the Mirror Worlds of Highlight Ryōshū and the other House of Spiders Identities had been grouped together, and corrected it through a subsequent hotfix

Two issues occurred through this series of events, and we plan to fix them.

• First - Information was not aligned across teams during the design and integration process between the Highlight Identity's Story and the other Identity Stories
• Second - It is simply that I should have confirmed and approved important plot-related elements.

The company and teams have grown in scale since their founding, and so has the scope-and-division of tasks. As the director, it is my duty to properly recognize which parts I need to check or confirm through the end, and which parts are to be entrusted to the teams. I regret to say that my failure to do so has led to the current issue.

Words couldn't describe how sorry I am that, due to this issue, users who had been closely following the tragic or unexpected plots of the Sinners across their myriad Mirror Worlds were made to feel as though an engaging plot element had been abruptly discarded.

Both the teams and I will seriously reflect on the two issues mentioned above and pay closer attention so that they do not happen again.

I am truly sorry that this issue occurred on what should have been a fun and exciting release day for Ryōshū's Highlight Identity.

We will continue to be mindful so that the plot and setting of the universe-building can be better coordinated to make the game and story experience more immersive. We will also further reinforce our communication system.

Once again, I sincerely apologize.

Hello, this is Project Moon.

We would like to inform you about the known issues identified after the Apr. 30th Scheduled Update, and the ETA for a Hotfix that addresses them.

Please continue reading for more information.

[ To be Hotfixed ]

▶ An issue in "Reflectrial][lairtcelfeR" where, if the boss unit has entered Phase 2, the game fails to respond when battle is resumed with the subsequent Team Loadout

[ Issue Cause ]
– With Ver. 1.104.0 Update, the "Docent" Trait Keyword, which was missing in the previous version, was added to the affected boss unit. An erroneous logic in this process caused the game to become unresponsive after the boss entered a new phase.
※ Relevant Bug Fix: Fixed an issue where a specific Keyword was missing from Phase 2 of the boss unit appearing in "Chapter 9.5 - Twining Threads"

[ Issue Fix ]
– The "Docent" Trait Keyword on the boss unit will be removed via a hotfix as a temporary solution to the progression blocker issue.
※ Please note that the bugged logic will be corrected with the next Scheduled Update.

▶ An issue where, in the Nocturnal Sweeping BokGak Reward Exchange menu, a certain reward item is shown and exchanged in incorrect numbers and rates
※ Relevant Item: [Season 7] Egoshard Crate
: This issue was fixed on 4/30 14:03(KST), and will now yield 5 Egoshard Crates instead. The displayed number in the Reward Exchange menu will also be updated once the hotfix is deployed.

※ For Managers who have exchanged the item between 4/30 12:00 ~ 4/30 14:03, please note that we will be providing the correct amount of the said reward item in the future based on its mismatched quantity.
We will share further details regarding this matter at a later date.

[ Hotfix ETA ]
– 4.30 (Thu) 17:00 (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.
