Before upgrading, empty valuable racks and copy the full save folder; if loss occurs, stop creating new saves and evaluate the developer-described .bak1 recovery method.
What is verified
- The original house-upgrade loss report was isolated.
- A developer supplied the save path and .bak1 rename method in response.
- Additional launch-window upgrade-loss reports are community observations, not a universal diagnosis.
Prepare 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 truly absent rather than relocated, then close the game before inspecting files. Preserve the current folder even if it appears damaged.
Attempt recovery reversibly
The developer described renaming the matching SaveSlot_X.es3.bak1 file to SaveSlot_X.es3 after protecting the full 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.
Frequently asked
Questions about fell and sell shop upgrade lost items
Should I empty racks before upgrading?
Yes. It is a low-cost precaution while upgrade-related rack loss reports remain under monitoring.
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.
