I aswell have had a doll bug. Every time I get a doll, I can use it for about 5 minutes or less, then it just disappears. I'm not sure if it's just me though. I already reported it to Snake Rekon and NCJohn which they said I may just have to buy a new doll system. Although I play the facebook version more, even before the facebook and the identity system came out, it's still been like this.
