I do have that checked in this case, but it's not helping because there is an indirect route to the target.
Picture being a seeker on the top end of the letter "C" and being told to move to the bottom end point. Let's say you start out rotated to the right, and therefore have to rotate to the left to continue moving along the path of the letter c.
The minute you start rotating downwards to turn left, you end up being pointed towards the destination, even though it's not along your path. Therefore you start moving forward again as you keep rotating to the left. Not sure if that makes sense, but that's what I think is happening in this circumstance.
