3.0 has been the most bug ridden experience I've had in a game for quite some time. Really inexcusable bugs, like being locked into certain menus and not being able to do things I know I can do. Then we get to the absence of features: still no MC and Wings. Still no outfitting in MC. There is no reason for these two, they are an arbitrary limitation that serves only to frustrate.
3.0 fixed a great many things but it ignored a very large number as well.
For me, personally, this has been the smoothest, most bug-free Update I have experienced yet. The only issue I'm having in game is an issue I was having back in 2.4, so won't blame 3.0 for that.
