Sadly, they did not do this for the houseboats, probably for reasons mentioned above about how they made the walls. My alt has a Victorian and i saw that NC in there, went back to look at the houseboat packs - nada. Luckily, i am using a dark color in a small space so with lighting effects, i think i can hide any small mismatch but i would want more precision for a Victorian, yes. I cant wait to see what all you color experts have been doing to your Victorians!
