Then the episode 4 you downloaded must be entirely different than the one I did.
As for the posts calling for a separate thread to discuss animation issues, well, I just think that's silly. What we saw in episode 6 may be an isolated case. We may only see it for an episode or two, we might not see this problem again for the rest of the series. The discussion is totally on topic, as we are discussing the art and animation of episode 6.
