Yes the pet is basically a test ATM, as there's only one and there's a lot with it that is wack. The battle sprite was removed since it was causing issues, including Punnai's. I was not aware of party members becoming leaders after Transformation of Kunnai. I have found the bug and fixed it for next update. Sadly with Itchio's state right now I can not assure when the next update will roll out. But it will be available on Patreon for sure, until this mess is fixed.
