Update 4 (2026-08-27) officially addressed this plaster issue: A completed plastering objective becomes unchecked after loading. 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
A completed plastering objective becomes unchecked after loading.
Check before changing your save
Inspect the repaired area and objective together; a lost tick does not necessarily mean the wall needs new filler.
- Confirm Steam has completed all available updates.
- Inspect the repaired area and objective together; a lost tick does not necessarily mean the wall needs new filler.
- Do not apply more filler until you have isolated the changed area.
Official fix versus your current save
The developer's Update 4 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
Do not apply more filler until you have isolated the changed area.
- 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 plaster, the exact objective, installed build and reproduction steps to the developer's Steam discussion board.
