- Added a Bongbong accessory to the pistol when Nell wears the Abyss School costume.
- Fixed an issue where the next round would start even after a forced round termination in Survival Mode.
- Fixed a bug where the difficulty of rounds 11–20 in Survival Mode (Hard Mode) was locked at round 10.
- Fixed an issue where the sound effect for Delsi’s shotgun hit would overlap.
- Improved an issue where a fatal error would occur in the costume menu.
- Improved an issue where a fatal error would occur while playing Survival Mode.

※ We have received reports that fatal errors continued to occur even after our previous update, which was intended to fix them.
In our testing environment, we mistakenly believed the issue was resolved as no further fatal errors occurred.
In this version, we have made further improvements to the suspected causes of the fatal errors.
We sincerely apologize for not providing a stable gameplay experience and will strive to conduct more thorough testing.
Thank you.
