not sure if it was reported or not, but Vivica scenes has a lot of missing words, probably refering to how she calls lucina. Some examples:
when talking about the day of the attack (quest sadness)
When talking about her changes (quest changes):
and the quest befor sadness also has those missing words.
Maybe cause at the start of her quests there is no input to how she calls lucina? tough in the first scene she calls her the same as what you call her
