The Replicants have Athlete, Courtesan, or Outdoorsman at 4 for free, as mentioned on page 38. The table on page 72 and the stat-block NPCs were written before that was added, and are incorrect. They will be updated in the next release.
The Roamer special benefit listed on page 31 should refer to Twists rather than "plot points." Ditto for the Tao benefit on page 24.
