I seem to remember that there was a flying Deathclaw-bug in F3 too. It kinda ascended to heaven and then smashed down to earth again later.
I had two lockups and one texture-fail in my three days of playing the game. Picked up Veronica on the way, what a nice girl. Now I´m trying to do her quest along with the vault 22 one but I can´t seem to finish the quest cause I need to
The only thing that really bugs me is that feeling of "there´s fifty thousand more quests for you to dooooo" looming in my mind...okay it´s just 136 or something, still. A lot to do. Then again, the first playthrough is just there to test the waters...
