Jesus, what's the point of having a beta when they don't fix the bugs the beta introduces? Disappointing, Bethesda.
To be fair, the beta doesn't seem to have broken anything this time around...at least not that was found. (I did have one out of the blue CTD, and I haven't had one of those since 1.3. I also got my first ever surprise naked courier and a dragon that wouldn't cough up its soul.) There wasn't much testing done, given the short beta period and general discouragement after what happened with the 1.6 beta. That was a no-win situation, really.
On the other hand, 1.7 also didn't fix bugs introduced by 1.6 that should have been fixed before 1.6 got drop-kicked out the door. That's my only problem with 1.7 thus far.
