can’t click sim, can’t click phone on sims 3

@Aprilxoboo  Do you use mods, or would you be interested in trying some?  Because now would be a good time to add a few, specifically NRaas ErrorTrap, Overwatch, and MasterController.  The first two clean up errors and stray data on their own, with no need for user input; MC doesn't do anything unless you use it to issue a command.  In this case, I'd use MC to reset the entire town—click on City Hall and select:

NRaas > MasterController > Town Options > Reset Everything

If you don't want to use mods, try evicting the household in Edit Town and placing the sims back in their house.  They'll keep their jobs and opportunities but lose their promised wishes and opportunities.

With either approach, delete the five cache files in Documents > Electronic Arts > The Sims 3 before you start.  For reference, they are:

• CASPartCache.package
• compositorCache.package
• scriptCache.package
• simCompositorCache.package
• socialCache.package

After you try one of the approaches, use "save as" to rename the save, so the original remains intact as a backup under its previous name.  Then quit, delete the cache files again, reload, and see whether the problem is resolved.
