Ok, not a big deal but I thought I'd post a question and see if anyone has any ideas. I'm on my third time through the game. This time I futzed around a lot and did a lot of misc tasks and finished the original quest about level 26. Then I started broken steel and thought i might play through Operation anchorage first. I tried activating the quest, following the arrow to the door where you go through the underground till you get to the escalator going up where you meet the paladins to start the help the outcasts quest. But when I go up the escalator, no matter how I do it, I freeze about 70% up the escalator. I think it's when it's activating the scenery of this added location.

Anyone have any idea what might be happening. I'm about level 28 now. I don't need OA's stuff, but I'm just messing around. Is there a workaround to get to the top of the escalator? Thanks.
