Update 6 (2026-09-21) officially addressed this mission progression issue: Loading returns the mission to a previously completed stage. If it still occurs after updating, treat it as a possible regression or different cause, not a guaranteed repair of your existing save.
Match the symptom
Loading returns the mission to a previously completed stage.
Check before changing your save
Compare the stage label, required object and current character interaction, not just the room's appearance.
- Confirm Steam has completed all available updates.
- Compare the stage label, required object and current character interaction, not just the room's appearance.
- Avoid clearing a whole room again until the stage mismatch is documented.
Official fix versus your current save
The developer's Update 6 note establishes a historical fix for this symptom. It does not publish a universal recovery command or prove that a previously damaged save will repair itself. This guide has not independently retested your save.
Recovery decision
Avoid clearing a whole room again until the stage mismatch is documented.
- If the installed game is older than the named patch, update and retest the same action.
- If the issue persists, try an existing known-good save without overwriting the failing one.
- If it repeats, report mission progression, the exact objective, installed build and reproduction steps to the developer's Steam discussion board.
