They have. At launch, the Enhanced Edition had numerous bugs and glitches. Approximately 3 weeks later, they released a massive bugfix update and it's helped a lot. I own the Enhanced Edition, and have only encountered some minor issues that are usually solved by just reloading the save file. They are working on the console edition, but pestering them for updates won't do anything. As I've already said, go to the Announcements section for any news about the Enhanced Edition
