Yea if u put it on pause to much, the age stops dead in its tracks, so it cant transform. it happpend to me. instead of putting ur tama on pause when u go 2 bed, hit the middle button, than the first button and the last button at the same time or 1 after the next. then set ur tama to anything AM (for example, 2 AM) and it should fall asleep. i do it all the time when i go to bed and school. it really works.
