Emma was changed because arc put out a poll same with Jessica this is just a rework the story is remaining the same unless you want to go back to the old version where the code is a mess and super sloppy.
Change is normal to not like but this was needed so Arc can have more freedom to do whatever he wants plus he's adding more events to everything all girls are hopefully getting kids and if arc forgets any he gave us permission to hit him with tennis balls!
