Corrupt file on The Exchange

In June 2010, several players noticed that a package file was attaching itself to other packages in The Sims 3. The file was a corrupt girl doll, incorrectly cloned from the teddybear. Simmers became 'infected' by downloading lots, houses or Sims with the hidden doll attached, similar to the way many computer viruses spread, and the doll was determined to cause longer loading times and even game crashes.

Many The Sims community sites began reporting the issue and a simmer named glitzyangel posted a guide on how to get rid of it. After a while EA responded with a sticky on their forum, informing the community about the issue.
