the first time I ran Washington Hotel Open Beta when I got to the barrier that has to be destroyed to proceed my character still could not pass through that corridor spot even after the barrier was destroyed. I logged out and tried again but it still did it. Even when I joined another player and he was able to walk through that spot I still was hitting the invisible wall. Only after I terminated the game and restarted it was I able to get through that spot without a problem. In the closed beta I didn't have this problem but did have the invisible wall in the garage.
off topic, also in one mission the light machine gun reload sound was absent or silent for a little while
