The codework needed to be done, it was actively preventing coom from being added to the game, so they bit the bullet and fixed it. Writing now has its own dedicated writers, and, as far as I am aware, it doesn't really affect how quickly things come out.
They're actively working on adding cuddling and threesomes to the game, two very requested features, which does require some code rework. The second-largest obstacle is that they don't have the funds to have the artists pump out artwork that fast, which significantly delays things.
