If an upgraded shop appears to have lost items, preserve the save and check the current inventory and Construction Chest first. Several related disappearance scenarios received August fixes, including recovery of qualifying old furniture. Manual .bak1 restoration remains an older developer fallback when the required state still exists in a backup.
What is verified
- The original house-upgrade loss report concerned the demo in July; its developer reply is dated July 21.
- A developer supplied the save path and .bak1 rename method in response.
- Ver. 1.1.3 specifically directs qualifying previously lost furniture to the Construction Chest.
Version-aware guidance
What changed recently
August 27 addressed new-shop disappearance; Ver. 1.1.1 addressed house wiping; Ver. 1.1.3 introduced a Construction Chest safety net for qualifying lost furniture. September 4 added three new shop properties.
Read the dated update timelinePrepare before the upgrade
Remove valuable items from weapon and armor racks, note important quantities, close the game cleanly, and copy the complete save folder. Keep the copy outside the live directory with a date and time.
Leave enough ordinary stock and cash to verify the upgraded shop without immediately changing dozens of other variables.
Stop and document a loss
If items disappear, avoid repeated saves, further upgrades, or restocking the same racks. Capture the game version, upgrade type, item stacks, and the first moment the loss became visible.
Check whether the items are absent rather than relocated. Ver. 1.1.3's Construction Chest safety net primarily concerns saves upgraded from 1.1.0 or earlier; it is not a promise that every missing rack item is stored there. Separate fixture loss from stock loss and preserve the current folder even if damaged.
Attempt recovery reversibly
Ver. 1.1.2 introduced automatic save repair and recovery. If those systems and the chest check do not resolve the problem, an older developer reply describes renaming the matching SaveSlot_X.es3.bak1 file to SaveSlot_X.es3 after preserving the folder. Follow the dedicated recovery guide one slot at a time.
This procedure is case-specific and cannot guarantee the missing items exist in the backup. Restore the protected copy if the result is worse or unclear.
Outdated advice to avoid
A launch upgrade-loss report should not label all current shop upgrades unsafe. Check automatic recovery and the Construction Chest before using the older developer reply's manual .bak1 method.
Frequently asked
Questions about fell and sell shop upgrade lost items
Do current shop upgrades always lose items?
No such current universal problem is verified. Related launch loss scenarios received official fixes; keeping an inventory note and a save copy is preparation, not proof that an upgrade will fail.
Can a .bak1 file restore the items?
It may if the backup predates the loss, but the developer-supplied method is not a guarantee and requires a full-folder copy first.
How was this guide verified?
Reviewed September 19, 2026 against the linked official Steam announcements. Ver. 1.4.3 is the named patch baseline; the September 18 public Dungeon Update is distinguished wherever it changes earlier advice. Older developer replies and community reports retain their original dates and labels.
