Moveobjects

Moveobjects is a cheat present in every base game that disables many of the normal restrictions on the movement, placement and deletion of objects (including Sims). This allows players to move or delete Sims, move or delete fixed objects (e.g., the mailbox) around a lot, move or delete objects that are currently in use by a Sim, place multiple objects on the same grid tile, or place objects in locations where they otherwise cannot be placed. In The Sims 4, Moveobjects cannot be used to move Sims.

Hazards
Moveobjects disables restrictions on deleting many objects that appear in the game, such as the mailbox, trash can, carpool, or the portals that allow Sims to enter and exit a lot. In most cases, it is impossible to replace these objects after they are deleted as the objects cannot be purchased in buy mode. This is a particular hazard in The Sims, as buy mode does not have an Undo function in that game, although build mode does.

Misuse of the cheat can also cause numerous glitches, though they are typically not severe and can be corrected. In The Sims 3, putting a Sim on a pedestal will cause Sims to be moved off the town grid. This can be reversed by activating the teleportation cheat and having the Sim teleported to a location in the town. Deleting a chair when a Sim is on it will cause the Sim to freeze until the game is restarted. Moving Sims with the moveobjects cheat can also sometimes cause Sims to sink through the floor randomly; this can be corrected by use of the  cheat.
