1: went into hyperspeed, my tama grew up within a 1/2 hour, had a baby, did hyperspeed, baby and parent fell on their face, with skull, buttons wouldn't work, both died
2: My tama changed from bad to good (one time falling on its face, next time jumping for joy)
Extra: I don't know if this is a tama trouble, but:
I lost my tama for 6 days and found it, stuffed behind the cushion of the couch, dead
