Character bug at Leoric's passage

I entered Leoric's passage and managed to walk a few steps until the video sequence started. When the video ended, I could move around, but not attack the skeletons as usual. Whenever i fired with my crossbow, the arrows spawned at the point where you would normally stand after the video.
I killed the skeletons by letting my arrows spawning at this point and then I went up to this point again with my character and it became normal.
