Ratatan Early Access Hotfix v0.5.13 Fixes Save Crashes

Ratatan hotfix v0.5.13 resolves mid-battle save bugs, corrects Cobun HP scaling, and adds sound volume adjustments.

Hotfix v0.5.13 for Ratatan addresses critical save data stability issues, character behavior errors, and audio bugs.

Save Data and Progression Fixes

The patch improves save data stability and resolves an issue where saving mid-battle with an active buff prevented the game from resuming. It also fixes a bug where the game skipped straight to the next phase if the Ratakaruta selection screen remained open until time ran out.

Character and Combat Corrections

Cobun behavior after resuming a mid-battle save is corrected. Effects that constantly reduce maximum HP, such as certain Decorunes, now stop at 1 HP instead of reducing health to 0 and causing Cobun to stop moving. Multi-hit Cobun attacks now perform critical hit checks on each individual hit, and the Ratatan now speaks when first selected in the formation screen.

Audio and Multiplayer

Players can now adjust volume directly within the sound options. In multiplayer sessions, a fix ensures that other players' voices now play correctly.

Why this patch matters

This hotfix targets progression-halting save bugs and broken character behaviors, making mid-battle saves reliable.
