I've had a whole host of bugs, but this one is about to make my head explode, since it renders all of my progress useless.

I was able to jump over the mountains that block the way around Lonesome Road (the gateway to the the big empty valley on the West side of the map). Once in the valley...I can't get out. I am on top of the mountains and can drop down to Lone Wolf Radio trailer, but it's like I'm at the end of a game map - I can't move any farther that the edge of the mountain base. And this is all the way around the mountain base, so I'm trapped here.

Now here's the best part: I tried to load previously saved games, and all of my previously found locations have disappeared off the map.

I have to echo other users's sentiments - I expect bugs in a new release of anything, but this is unacceptable. Aside from the general frustration, I honestly feel like Bethesda should be paying ME to test this damn thing. I paid the same amount that someone else will pay for this in three months when these bugs are fixed. How could this have been released in such a poor state?
