[Key, Rewrite Quest 26]

Please, someone!

[Key, Rewrite Quest 26]

I noticed this question came up way back in 2013 as well, but I didn't get/understand the answer there, so here goes.

I have completed all quests except 26 and 28 and gotten all friends except #100 (NOT quest 30, "100 Friends"). So yes, all routes + Moon and Terra completed.

I have followed the walkthrough for Quest 26 4 or 5 times now and gotten all the different seeds.

Here is the dialogue with Kotori on November 1st:

Kotarou: Anyway, I wanted to report on my see-planting progress
Kotori:  Okay, how many did you plant?
Kotarou: Something like this.
         I send Kotori the Mappie data showing where I planted seeds.
         Kotori is surprised.
Kotori:  Oooh, you're doing it! You did pretty well!
Kotarou: That's right, I did my job, didn't I?
Kotori:  Now if the town gets wiped out and five hundred years pass, the ruins will be covered in greenery and wild animals will be sure to come here!
Kotarou: I think that would happen to any city...
Kotori:  You did it, Kotarou-kun!
Kotarou: Y-yeah... I did everything I could for you.
Kotori:  I was worried I didn't have enough practice manipulating men, so thanks.
Kotarou: Hey!
Kotori:  Now I can hold my head high with the other wicked women.
Kotarou: Don't turn into one of them!
         Kotori is now "Ill-Natured Woman Level 1"!

Anyone understand why this is happening? Is there a patch I haven't installed?
