Check you list against mine and any of the missing ones are most likely the problem.
@Dazs, it's ok, I'll try to learn the forms and shapes, don't waste hours on that, if you already retouched them 4 times. I guess it's very much "YMMV" for many people and someone might ask for something else.
Well they ARE aliens after all, makes sense their designs are not easily understood

Seriously though, I do try my best to accommodate players when their concerns are valid and doable. There is an alternate mechanical looking ship pack for Hivers in the ZIP you may want to look over if bugs aren't your thing.
Thank you both for getting back to me, I am interested on your thoughts once you've played against them for a bit if you would care to share.
