BUG?: playthrough after Kyouko completion (minor spoilers)

[TenguSan]

After i completed Aselia's route and played the game the second time, she kept all her skills and level from being an Eternal (stats were reset to normal though)... In this same playthrough (2nd) i finished Kyouko's route.

I am now on my 3rd playthough and working on Esperia's route, and I just got Kyouko in my party again... but strangely, she has the skills and level of BEFORE becoming an Eternal.

while this is a minor bug, it is certainly a pain in the ass and uses up a lot more mana to get her up to the levels of the rest of the characters.

Someone reported a similar issue with Kyouko so I guess it's a bug and she doesn't keep her levels leveled while Eternal.
