What stays after a save and a load

What comes back after a load depends on the kind of object. The table shows each case.

Thing	Saved	Back after loading	Notes
A spawned item (Spawn.Item)	Yes.	Yes, with its stack, position and expiry.	It has no save id, so Find, GuidOf and mod data do not work for it. WorldItems.IdOf gives it a path-style id, <scene>/path:.... Items the player dropped in this session work the same way.
A spawned item’s expiry time	Yes.	Yes, with the time left.	Items run down on the game’s item timer. A timer that fires while the player is more than 10 metres away removes the item.
A scene object with a save id (IsSaved is true)	Yes, if it is switched on when the game saves.	Yes, into the object that is already there.	The game only saves objects that are switched on.
Mod data (SetData)	Yes, with the save.	Yes, when the save loads.	Kept by mod, scene and save id. Emptied when a load or a new game starts.
A scene object that is switched off when the game saves	No.	No.	The game’s save skips switched-off objects.

Things to know

• It is not known whether a spawned item stays when the player leaves its room. The game’s list of spawned items keeps its entries by object, not by scene, and this has not been tested across a scene change.
