Good job on the Venture Class package; it looks VERY nice. The neck looks like what the ship should have had all along; sleeker and stronger looking at the same time, and a logical step forward from the Galaxy Class.
Anyway, about the bug...there is a bug at the moment with the Galaxy hull; if one uses it in conjunction with the other Venture parts, the Galaxy hull ends up with Type 1 windows, whereas the rest of the ship has whatever window type the user chooses. I am able to reproduce this bug by using the Exploration Cruiser Refit (the one with saucer separation), and using the Galaxy hull in conjunction with the Venture neck and/or saucer. This bug does not manifest itself for me with the new version that came with the C-store purchase.
I don't have a screenshot, but I think this one's pretty self-explanatory.
