Ratatan Demo v0.3.78 Hotfix Addresses Crashes and Audio Bugs

The latest Ratatan demo hotfix resolves multiple stability issues, fixes camera bugs between worlds, and applies audio volume sliders to system sound effects.

Developers have deployed hotfix v0.3.78 for the Ratatan demo, targeting critical multiplayer crashes, progression locks, and audio issues. The update also introduces interface indicators for newly unlocked items.

Stability and Progression Fixes

The hotfix resolves a crash that occurred when a multiplayer session was terminated or disbanded. A bug causing the game to freeze after sorting and switching tabs on the quest board is fixed. The update also prevents a progression halt in the tutorial caused by Advanced Settings rhythm commands and fixes a bug where boss attacks stopped registering if the pause menu remained open.

Camera and Environment Adjustments

Transitioning from World 1 to World 2 no longer leaves camera settings in an unintended state. A separate camera bug triggered by touching the healing spring immediately after entering World 2 is also fixed.

Audio and UI Improvements

System input effects, such as shop purchases and menu unlocks, now correctly follow audio volume settings in the options menu. Newly unlocked enhancement items now display a NEW marker in the player enhancement menu. Non-Japanese and non-English language settings no longer display overlapping text during the opening tutorial sequence.

Known Issues

Developers are investigating ongoing bugs, including boss behavior cancellations, missing sound effect jingles at the start and end of boss battles, and a known issue where in-game music and the rhythm gauge fall out of sync.

Why this patch matters

Hotfix v0.3.78 removes major roadblocks like multiplayer crashes and soft locks, making the demo much more stable while developers continue investigating remaining audio and rhythm sync bugs.
