Rolling back a griefed area hands out duplicated items

Restoring a chest area from an old backup is easy, but players have moved things in and out since then. Done naively, the loot of honest players exists twice, deposits vanish and the thief keeps the prize. Here is the bookkeeping that avoids all three.

Why this works

Things move between places, and an old snapshot knows only where they were. Putting the old picture back creates a second copy of whatever left since. Following each movement and settling it keeps the total of every item the same as before.

When not to use it

Do not use it when you cannot tell who moved what, such as with no transfer log. Then a full restore with an apology, or compensation from the game team, is fairer than guessing. It is also too heavy for one stolen item.
