Aha! What a bunch of bull! For the price in simeoleons it should clean itself by default, not to mention that you'll be forced to make a sim in the household have a mechanic skill. Is it also unbreakable then? I can comfirm that I had a sim upgraded it and it does clean itself after the upgrade.
After the my sim upgraded it to clean itself, it also got clogged! It plays the music and cleans itself though.






Suddenly I couldn't see my store content but modifying the cfg file did the trick.
My game just crashed and ended without any error messages. I have removed the 5 custom hairs I had installed and still get the same results. I have no hacks or mods, just the many items I've got from here using the compressorizer. Since insalling WA my game often CTD but this time closed completely. Please advise.
