In lesson 2.4 Catching a Ride at the part where you can Role play as Kenny or Sayaka the last line is mixed.
So while roleplaying as Kenny the last sentence is spoken by the "real" Kenny and does Sayaka not completly says her line. (Same when role playing as Sayaka, but then vice versa).
PS: Just a minor thing though. Does not make me love Rocket Japanse less.
Mixed audio ath the Role play parts.
