It seems that every time I use something, it breaks. I fix it and then when it gets used again it breaks. Even if I replace the item with a new one, first use will break it again...
I've tried the bath, shower, piano, computer, dishwasher, trash compactor, spa, stereo... It all breaks. Has anyone got any ideas why?

Edit: It only happens in the one household.

Yes, you've probably been clicking things on the testing cheats menus that you don't understand. I'm guessing you spawned the break inducer; shift click in your sim and spawn the break suppressor to cure it.

I don't remember spawning the break inducer... the break suppressor seems to have worked though. So far so good.
Thanks for the quick response.

Well done, glad you fixed it! *wags finger* don't click that break inducer again!
