[Notice: Refraction Railway Line 5 Optimization Issues]

iOS) We have identified an issue where the game may crash in Section 3 of the Refraction Railway Line 5 when played on a device with 4GB or less RAM.
The same issue may occur on other non-iOS mobile devices with 4GB or less RAM.
We have investigated this issue, and discovered several points where unintentional RAM usage spikes occur. The following are the said points:

• Instances of effect objects for certain Identities or Peccatula Invidiae that has taken the form of certain Identities
• In-game font resource loading duplication
• Certain dead characters' resources lingering in RAM

We are currently working to improve optimization for devices with 4GB or less RAM by resolving the above issues.
Please note this information before entering Refraction Railway Line 5 with devices with the above settings,
and for now, we would like to recommend using devices with more RAM for Line 5.

We will keep you updated on the progress and deployment status of our optimization process with our future update notices.
We sincerely apologize for the inconvenience.
