@Cinebar gimme your computer ahah because I have also a lot of gigas of cc as you and it stil crashes despite all the cares I do with my cc. I noticed recently that also the cc that kept the texte and the description of the cloned object makes the game not stable.
I also have custom houses I decorated I saved in s2pack they are not playable at all always crashy .
If the cheats codes makes the game crashes I swear I cannot
Anyways I don't play it anymore I am so angry with this game. I switched to ts4 and I kept my sims 3.
