In the process of making a Sato, I transferred my Kaitabha to my FOnewearl and turned it into a Ribhava and got it to level 52. I logged on a few hours ago today to level it more, and found that it had reverted back to a Kaitabha. I leveled it once in an attempt to get it to return to Ribhava, but it remained a Kaitabha.
