I noticed a few other people have had the problem of trying to sense, then move in problem 1.4, rather than move first, then sense. I spent half the day yesterday trying to figure out what was wrong with my code. After making that quick fix, everything magically worked.
I wanted to suggest putting a short, 'Common Problems' video up for some of the more involved homework problems. This wouldn't be about problems with understanding of the material, but rather with stupid little errors like this that a lot of people tend to run into.
To that end, I wanted to open up the floor for others to list what problems you have had so far, in either the homework or the quizzes, that made you smack yourself in the head after realizing your mistake.

I added a little tip to the bottom of the video.
