A grid inventory loads with overlapping items after an item or bag changed size

Items that fill several squares of the bag are saved with their positions. When an update makes a sword longer or the bag smaller, they overlap or fall outside. Here is how to keep what still fits where it was and place the rest, without losing anything silently.

Why this works

The size of an item is a fact about the game, not about the save. Trusting the current game for sizes and the save only for the player's choices of place keeps the arrangement the player made, and a fixed order of placing makes the result the same every time.

When not to use it

Do not use it when the bag has no grid, such as a plain list of items, or when sizes never change after release. Then it is needless work. If a change is large, tell the player and let them sort the bag by hand rather than moving things unseen.
