Re: Who?
I don't mean to comment on the topic at large here, but your post makes the kind of assumptions that non-programmer bosses and customers tend to make.
The fact the "bug" existed in the previous release might have had far-ranging implications on the game's quality. It may be that it was a "Bug" (it would seem weird that women couldn't marry), and that by not fixing it - the game would stop being able to progress, not be able to load a savegame later, miss out parts of any plot, Not be able to draw animations and bug out. There are endless possibilities on why that might be a "bug" and not a moral thing.
The issue I experience is: I get given spec, and deliver that spec - then people want to change it AFTER the product is delivered, and assume it is trivial to do these things.
I am not having a dig at you Steve, but I am not looking to going back to my desk on Monday, and your post fired a million resentful neurons.
