@Biskup, really weird. I ordered from the first edition of that set and the figs I received were really good looking. I don't know if the kits from Michael's new caster are better than the ones that I have. Or maybe the caster buggered up the moulds with later castings…
Just reach out to Industrial Mechanika, he'll hook you up with replacements (I had a part missing from my Remora and had it replaced within the week â€" across international borders to boot).
