Why can't I trigger Anette's 7 heart event? (Frontier) Options

[beatrice15]

I'm in Year 3 with Anette at 10 love and friendship points but I'm still unable to trigger the event where she collapses outside my house. I recieved her mysterious letters and also talk to her everytime she's tired from chasing monsters (about 10+ times) but the event still hasn't been unlocked. Can anyone help? And also is it possible to skip past an event due to love points being too high?

I have checked all questions on various sites and also searched through walkthroughs but nothing has been able to help.

Thanks for your answers so far everyone!

Let me provide some more information:

Anette hardly gets tired anymore, it only seems to happen once a fortnight, she doesn't talk about getting chased either, although it used to happen alot. She doesn't give any hints about it, just saying about how she feels good recently and saying my character used to be sickly but is now buffed?

Mist is around, she's at 10 love and friendship points. I'm not very far into the storyline:

I haven't completed the Lava Ruins yet, I've got to the point where I can access the big tree on Whale Island but I haven't been to the very top yet, Kanno has warned me about the runes being depleted and I should look out for where more runes gather. I'm at 10 love/friendship points with everyone in the village, and I've also experienced a few dreams - the last of which is where there are some scientists panicking about a rune facility blowing up.

Also, I've recieved Brodik's letter of challenge but haven't battled him yet.

I doubt any of these could make a difference of being unable to experience events with Anette but do you think it's possible?
