Re: Time Traveler Broken Into the Future Corrupts Entire Saved Game
@Ephendrielle For travel transition issues, the best combination is NRaas ErrorTrap, Overwatch, and Traveler. These three will work in the background to repair glitches and low level corruption without your having to do anything. MasterController is also useful for its ability to manually reset sims (it's much more thorough than the cheats console option, which only resets a sim's location and clears the action queue). You can also ask questions directly on the NRaas website—its mods are still actively supported by the developer and site admins.

Be sure to get the appropriate version of ErrorTrap for your patch level; there are different ones for Origin/1.69, Steam/1.67, and disc/1.67 (or mac). The other mods will all work equally well on both patch levels.
If you've never used mods, the easiest way to start is to download the Mod the Sims mods framework, unzip it, place it in your Sims 3 game folder in Documents, and delete the five cache files inside the game folder. (These are CASPartCache, compositorCache, scriptCache, simCompositorCache, and socialCache.) Once you've confirmed that the two sample mods work, you can keep or delete them as you prefer, then add the NRaas mods you want—they'll all go in Packages. Be sure to delete the cache files any time you add or remove a mod from your game folder.
