so i have overwatch and every few minutes the game freezes and it says that some sim have script error , what does that mean?
thanks in advance

Mostly it means just what it is saying. Something in the game is causing errors for the sims. To get any better answer you would probably have to ask over there, since there is a policy that creators support their own work.

Or you could try tracking the problem down yourself. If you are lucky, it's something simple like a mod that needs to be updated. The Game Problem FAQ can walk you through the process if the error logs that Overwatch dropped into your Documents/Sims 3 folder don't give you any clue about what was causing it.

Maniaco meant that overwatch was detecting an error, not that there was something wrong with overwatch, Ghost.
OP, you need to do the half swap shuffle to figure out which mod is causing your error, unless you want to use S3PE to open each package and find out which one has the script that's named in the error.

When Overwatch finds an error it usually also provides an error log file detailing the error that it found. It's an xml document, and it can be hard to understand, but it's there and it can be read. And sometimes they can give a clue as to what was happening, like when I had a fairy with a Green Thumb getting reset due to script errors, and every time it happened she was apparently harvesting a money tree. When I locked her away from the money trees and had her non-green thumb husband handle those, the problem stopped.
