Last Thursday night I went and picked up my box set, I did open the box lid but only made sure all 5 figures were there and no major cosmetic defects, then brought it home.
Later at home I did a more thorough check and removed the insert foam, found out Landshark's instruction sheet + character card bag was missing.
Next day at the Yardhouse bar meetup, I consulted this issue with our helpful Seibertron people (Thank you!!!), and they gave me a very good advise to talk to Pete next day morning at Botcon, which I did and he just gave me a replacement one straight. Awesome!
