I also have the "wrong head problem".
Well, I think this is a core mistake by lego: The instruction booklet tells me that the missing head must be ElementID# 4506812. But in the official set list on the lego-website (Bricks & Pieces), it is listed as ElementID# 6123702. And this is what we actually got from lego.
As I checked my set, I also noticed that I have the "hull piece problem" that is mentioned in the nitpicking-part of this review. Since this is my first lego-ship, I don't have the opportunity to compare it. But when I assemble them, it also feels like the parts doesn't really fit together.
And at last, I also noticed some other small quality issues:
1. The colors of the hull pieces differ from each other (like one is more red brown, while the other is light brown and the next ist more orange brown).
2. Some edges of the hull pieces have small notches (looks like kind of used bricks to me ... or like they were all mixed with small stones in a washing machine - well, you surely know what I mean ;-)). I first thought this is because of the loose packaging of the 3 middle hull pieces (kind of damage during shipment), but I also see some of this "notches" at the front hull pieces (which were delivered in a bag). And when I put the pieces together as needed, I notice the "notches" even more :-(.
So, this is the first time that I am really a bit dissappointed of lego.
