STEP 01
Close the game completely
Do not edit a save while the game is writing it. Also close launchers that may actively synchronize files when practical.

Save editors without losing progress

STEP 02
Make an untouched copy
Copy the whole save slot/folder, not only one obvious file. Put the backup outside the game's save directory and give it a timestamp.
STEP 03
Record game and tool versions
Save formats change. Note the game patch and editor release before editing so a failure is reproducible and reversible.
STEP 04
Change the minimum
Make one group of changes, save to a new output if the tool supports it, then launch and verify inventory, quests and loading before further edits.
STEP 05
Restore the whole backup on failure
If the game reports corruption or behaves strangely, stop editing and restore the untouched folder rather than repeatedly rewriting a damaged save.
