They don't care about bugs.. so why not add stuff to keep players interested? new features gain users and $$$.. bug fixes don't.
I learned LONG ago that the devs won't address any bug directly unless it alters their revenue stream. If it doesn't, suck it up and deal with it because they'll ignore it or just flat out deny it exists in the face of all evidence... or excuse it, a la "streaky ai" (RNG should NOT be "streaky")
