I managed to rollback a save (v1.98.158.1020) and upon gameplay, DD itself was very buggy. Sims would commonly stand completely still, sometimes permanently freezing until the save is loaded again. Not only that, the Hard Penis textures were bugged, that had null textures on them which I've never seen on Wicked Whims (Even with a custom Penis model).
I hope that the author will continue updating this, and I much prefer DD over WW, but it's back to Wicked Whims I suppose.
