Update 6 (2026-09-21) officially addressed this tiles issue: A tile placed without adhesive disappears on the next attempt. 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 tile placed without adhesive disappears on the next attempt.
Check before changing your save
Check the adhesive state of the exact target and whether the tile was placed or only previewed.
- Confirm Steam has completed all available updates.
- Check the adhesive state of the exact target and whether the tile was placed or only previewed.
- The fix is not evidence that adhesive is optional for normal tiling.
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
The fix is not evidence that adhesive is optional for normal tiling.
- 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 tiles, the exact objective, installed build and reproduction steps to the developer's Steam discussion board.
