I just found a bug where your character would immediately unlock the key options instead of sleeping, and if you try to ignore it...it still has the options. Turns out...even after the event, it has the options
Yeah this would duplicate the Key.
Just ignore it for now the patch is already planned.
Keep ignoring it to finish her event without failing.
If done enough times she would finish her Homework! And the event would end.
Thanks, will fix it!
