Keep a separate save before an uncertain puzzle or consequential choice. A quicksave is convenient, but relying on only one changing slot can remove the recovery point you later want.
Save for a decision
The current player guide recommends manual slots alongside quicksave and autosave. Use that flexibility deliberately instead of assuming the latest automatic save is always suitable.
Useful moments include entering a new dangerous area, changing a movable puzzle arrangement, making an uncertain dialogue choice and testing equipment after a reported crash fix.
A simple save routine
- Preserve a known usable point before the experiment.
- Save the current state in another available slot when you need to keep both.
- Make the change and inspect what happened.
- If you continue, avoid overwriting the earlier point until you are satisfied with the result.
- When comparing outcomes, label your notes with the location and build.
These are editorial habits, not a claim about unlimited slots or the location of save files.
Do not confuse load behavior with a reset
Loading restores the state represented by that save. It does not prove that a quest flag, random mutation or puzzle will be regenerated differently. Use a room’s documented reset control when the current patch provides one.
After a patch
Preserve the save before testing whether a known issue has changed. Patch 1.0.4 fixes several load-related effects and item cooldown behavior. If a problem persists, keep enough detail for a report rather than repeatedly saving over the evidence.
