Not at Maty, its at the InTeen site (by twojeffs) and there are a few more at Paladin's place (simwardrobe) too.

Well, so far the OBJ edition (that version, not the others) seams to be ok, of course you can never be 100% sure about anything. Even with previous eps and updated insim I'd encounter a few probs, but generally for basic things like buying clothing, change day/time, personality/turn on-offs, seams to be working fine. I even used to grow up sims already without any prob. Of course that's just my experience so far
