I am pretty sure I have followed the playthrough to the letter - her aff stat is where it should be at the previous checkpoint (before elven lands) - i've replayed the sequence New Yhilini a few times now and just can't get that one stat right. Affection is right for every other character.have you done all the dialogue? and the rp of the character talking with her are above the right threshold
the last dialogue ginasta-simon will play just before you leave again, after you decide to go to zirantia. it's a ginasta +2 if you have talked with vera (goddess of magic cult leader) in the govern 2.
