For PC players, finding the Insect Prison Remake save data is the first step to backing it up. Do not trust the Steam Cloud alone—multiple reports indicate the cloud sync fails after the Chapter 3 boss fight.
Upgrading between game versions can sometimes cause data instability:
: Updates may reset the Recall Gallery to fix previous unlocking bugs. Mobile Saving Bug
: If you're unable to find a solution, consider reaching out to the game's support team directly. They may be able to provide a fix or guide you through recovering your save data.
