Update 6 (2026-09-21) officially addressed this assembly issue: Loading a save made partway through assembly prevents further progress. 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 a save made partway through assembly prevents further progress.
Check before changing your save
Record which assembly stage was active, the selected tool and the next missing prompt.
- Confirm Steam has completed all available updates.
- Record which assembly stage was active, the selected tool and the next missing prompt.
- Try an existing save before the assembly if available; do not edit save files.
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
Try an existing save before the assembly if available; do not edit save files.
- 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 assembly, the exact objective, installed build and reproduction steps to the developer's Steam discussion board.
