Jessie's Essential Sydney Mod

GAME CHANGES

Makes Sydney essential (unkillable), with a caveat:

There's a very rare situation we must account for:

• []The player has Sydney as a follower during Stealing Independence,

  []The player then takes her into the Jefferson Memorial Rotunda before the scene in which Dad dies during The Waters of Life,

  []The player then tells her to wait in the Rotunda beyond the airlock and leaves her there,

  []The player then returns to the Rotunda to experience the aforementioned scene: Sydney will be standing there with Dad and the others:

  The game accounts for this; any followers left in the area beyond the airlock are killed by the radiation burst along with everyone else.

  Sydney loses her essential state if this rare situation occurs, and is killed.

  RATIONALE

  I have no rationale. I'm a big squish and don't want Sydney to die.
