this is new to me, where this chain of events start?mc.business.attention and mc.business.max_attention
Alternatively search for "You're glad to finally left alone, but the encounter has eaten up most of the day." in \game\major_game_classes\business_related\Attention_Events.rpy and add hashtag to the line below like this:
return #"Advance Time"
It doesn't change the frequency of the visits but it removes the annoying part about skipping afternoon every time she visits.
