Overwatch

Overwatch is a mod developed by nraas that attempts to correct known errors produced by the game in The Sims 3. It runs in the background and automatically attempts to correct any problems that it finds, such as unroutable Sims, corrupted game data, and references to content that no longer exist. It also performs a nightly cleanup (5am for urban world, such as Bridgeport; 3am for others) to reset various objects, delete abandoned vehicles, turn off televisions and stereos in inactive households, and recovers missing or abandoned Sims. The mod will produce a notification detailing its changes.

Overwatch creates a new pie menu entry on the active Sim and at city hall, allowing players to configure its settings. However, it is designed to work out of the box and can start working as soon as it is installed.

Overwatch has received praise for its ability to improve game performance.
